The bread & butter of every fantasy roster ? the running backs. Without a good one you?re dead meat, and last year that meant having St. Louis? Steven Jackson or San Francisco?s Frank Gore or, of course, San Diego?s LaDainian Tomlinson. Pro Fantasy Sports has compiled a deep list of running back profiles that is sure to keep fantasy owners in tune with every available prospect. This is the second installment in our annual release of profiles. Be sure to visit PFS daily in the coming weeks to see the rest of our profiles, and to check out our day-by-day release of team previews starting near the end of July when NFL camps open.

LaDainian Tomlinson, San Diego

Whether it?s catching, running or even throwing at times, Tomlinson can do it all. The NFL?s MVP boasted a whopping 28 rushing touchdowns last season, as well as three touchdown receptions for a grand total of 31 touchdowns. Needless to say, he?s easily the top fantasy player in the NFL, and he?s increased his touchdowns and yards in each of the last three seasons.

Lassan says: The Chargers offense could be even better in 2007 and that?s a scary thought in itself. Tomlinson is the best player in the NFL and should be the number one pick in fantasy drafts throughout the offseason. Put it this way: if you pass up Tomlinson you are either a fool or have some personal vendetta against him. Don't make that mistake.

Steven Jackson, St. Louis

Consider 2006 a breakout year for Jackson. Although his stats in 2004 and 2005 were solid, this was his first year without Marshall Faulk stealing some carries away from him, and head coach Scott Linehan made full use of his talents. Jackson topped 1,500 rushing yards and posted 16 total touchdowns, with a hefty 90 receptions. His 90 receptions were the most by a running back in the NFL last season.

Lassan says: Jackson has passed Johnson as the number two fantasy back; even if he loses 25 catches in 2007, he?ll still be the number two fantasy back. If you lose out on LaDainian Tomlinson, he?s a nice consolation prize.

Larry Johnson, Kansas City

Johnson entered 2006 on top of the fantasy world after ripping through NFL defenses at the end of 2005. Johnson wasn?t quite able to keep up that blistering pace last year, but he still posted 1,789 yards and 17 touchdowns while catching 41 passes. Additionally, Johnson posted 11 games of 100 rushing yards or more ? pretty impressive when you consider how sluggish the Chiefs offense was at times.

Lassan says: The workload on Johnson?s shoulders is a concern ? can he really expect to tote the ball 416 times every year for the next five seasons? I think not. Plus, the Chiefs have a quarterback concern and the offensive line is a little shaky. Johnson is still valuable, but definitely not top running back material.

Frank Gore, San Francisco

In his first full year in the starting role, Gore rushed his way into top five fantasy consideration. Gore busted through NFL defenses for 1,695 yards and eight touchdowns, while catching 61 passes for 485 yards. Overall, Gore posted nine touchdowns last year. The 49ers have taken steps to ensure their offense continues to improve this year, namely improvements with receivers and along the offensive line. The improvement bodes well for Gore.

Lassan says: Gore is a rising star at running back, and he will be even better in his second year of toting the rock for the 49ers. As long as he staves off the injury bug and the 49ers continue to improve around him, he?ll continue to move up the draft board.

Shaun Alexander, Seattle

Whether it was the Madden curse or just bad luck, Alexander just didn?t have a great 2006 season. After losing guard Steve Hutchinson to the Vikings, the Seahawks offensive line wasn?t the same; quarterback Matt Hasselbeck was injured; and Alexander missed six games with a foot injury. Considering he missed six games, Alexander had a rather average season ? 896 yards and seven rushing touchdowns ? his first sub-1,000 yard season since his rookie year in 2000.

Lassan says: Look for the seven-year veteran to bounce back and top 1,000 yards, but he?s probably not worthy of a top three pick this season. Alexander is definitely worth a first round pick, but is he breaking down?

Brian Westbrook, Philadelphia

When Donovan McNabb was lost for the year with injury, Westbrook became a bigger focus for the Eagles offense and he didn?t disappoint. After averaging 14 carries in his first seven games, Westbrook averaged 20 in his next seven contests. Additionally, Westbrook?s 240 carries in 2006 were the best in his career and he tied his single season high with seven rushing touchdowns.

Lassan says: McNabb?s status is a concern, but Westbrook is a great option for the offense. Don?t be surprised if Westbrook continues to see more action; if you like running backs to grab 80 receptions ? this is your man.

Willie Parker, Pittsburgh

Parker may not be the biggest back in the NFL, but that doesn?t slow him down. After busting onto the scene in 2005, Parker continued to rush his way towards top ten fantasy honors, as he totaled 1,494 rushing yards and increased his rushing touchdown total by nine last year. Considering Parker is a back who lacks prototype size, the Steelers have talked about getting Najeh Davenport more carries, just to keep Parker fresh.

Lassan says: The Steelers are going through a time of change, as longtime head coach Bill Cowher is gone and a new offensive coordinator is taking over. Fast Willie will still remain a staple of the Steeler offense, as head coach Mike Tomlin doesn?t want to change the run-first philosophy.

Joseph Addai, Indianapolis

Despite sharing carries with Dominic Rhodes last season, Addai topped the 1,000-yard mark and made Colts say Edgerrin who?? Although losing James was a big blow for the Colts, the offense never missed a beat. Addai stepped in and filled his role perfectly, especially with his 40 receptions and seven touchdowns on the ground. Additionally, he was a solid blocker for Manning, a plus in the Colts tough offensive scheme.

Lassan says: Addai is a star in waiting; with Rhodes out of the picture, he?ll get an even bigger workload in 2007. Although the Colts want to find a back to share carries, it?s going to be hard to keep the second-year back off the field. Give Addai one more year to develop and he?ll easily contend for top five honors.

Rudi Johnson, Cincinnati

Johnson isn?t the flashiest player, but he gets the job done every time he steps on the field. Over the past three years, Rudi has averaged 346 carries and 12 touchdowns, while topping 1,300 yards in each of those seasons. Although Johnson?s rushing yards and yards per carry dropped just a tad last year, he still posted a quality number of touchdowns.

Lassan says: The Bengals offensive line struggles likely had something to do with Johnson?s drop in numbers, but he?s still a steady player and will continue to post around 1,300 yards in 2007. Johnson won?t get too many receptions, but he?s still worthy of a top ten fantasy pick this year.

Laurence Maroney, New England

Even though Maroney was the backup to Corey Dillon, there was no secret he was the future of the team and it was obvious that it wouldn?t be long until he took over the full-time job. Maroney gets that distinction in 2007, as he?ll be the team?s number one back and look to improve off of his 745-yard total last year. Maroney?s production tailed a bit at the end of last season, largely due to a shoulder injury, for which he was forced to undergo surgery in the offseason.

Lassan says: Maroney?s shoulder injury is a concern, but if he?s 100% healthy in 2007 he?s a worthy top ten pick. Additionally, Maroney is young and has a lot of years left in his legs, making him an attractive pick for keeper leagues.

Reggie Bush, New Orleans

The Texans had to be kicking themselves after watching Bush dazzle in his rookie year. Although Bush only had 565 rushing yards, he made a great impact in the receiving department ? catching 88 passes for 742 yards and two touchdowns. Bush posted only one 100-yard performance last season, which came in week 16 against the Giants, but his job is to spell Deuce McAllister and be a change of pace back for the team.

Lassan says: Bush is no bruiser, but he?s got the talent to go over 565 rushing yards in 2007. Look for Bush to continue as a factor in the receiving game, but he?ll step it up in the running game as well this season.

Travis Henry, Denver

The departure from Tennessee means Henry will be on his third team in the last four years, but this is by far his best situation. The Broncos needed a go-to back and that?s exactly what they?ll get from this veteran. Henry is a good fit in the Broncos zone-blocking scheme and he should be a factor in their passing game as well. Even though the Titans offense was shaky at times last year, Henry rushed for 1,211 yards and seven touchdowns.

Lassan says: Henry?s approaching 30 years old, but he?s still got plenty of life left in his legs. The move to the Mile High City was a great move, especially with the better offensive line and targets in place. Call Henry a candidate for top ten honors.

Maurice Jones-Drew, Jacksonville

Jones-Drew may only check in at 5-7, but don?t let that fool you on the field. Jones-Drew carries a big presence, especially when you consider his 13 rushing touchdowns and 5.7 yards per carry average. The Jaguars selected Jones-Drew to spell Fred Taylor, but he eventually will take over his starting job. In addition to his 941 rushing yards, Jones-Drew tallied 46 receptions for 436 yards and two touchdowns.

Lassan says: The Jaguars will continue to use both backs, but I have a hard time believing Jones-Drew can continue to put up 13 touchdowns every year. Additionally, he won?t sneak up on anybody this year. Still a nice fantasy player, but he might be overvalued.

Edgerrin James, Arizona

Was 2006 the start of a decline in James? career? Well, that depends on who you ask. James had to deal with a rookie quarterback and a dismal offensive line in his first year with the Cardinals ? not exactly Indianapolis. James? rushing yardage fell by 347 and his rushing touchdowns dropped by seven. The good news? New Cardinals coach Ken Whisenhunt knows a thing or two about offense and new offensive line coach Russ Grimm will make the unit better.

Lassan says: There?s no question James struggled because of the offensive line, but don?t give up on him just yet. James may not hold the value he once did, but he?s not a has-been. Look for Whisenhunt and Grimm to improve the offense, but hold James value down just a tad until the offensive line shows it can consistently open holes for him.

Willis McGahee, Baltimore

A disappointing 2006 season and an overall disgruntled feeling got McGahee a ticket out of Buffalo. The Ravens needed a proven back to head up their running game and that?s exactly what they got in McGahee. The Ravens will also have to find the touch that led McGahee to rush for 1,247 yards in 2005 and not the one who struggled to reach 990 yards last year.

Lassan says: McGahee will increase his catches this year, as quarterback Steve McNair loves to throw short passes out of the backfield. The talent and pieces are in place for McGahee to have a big year, but he has only scored 11 touchdowns the last two years. For him to move up the fantasy charts, he needs to get into the end zone more.

Ronnie Brown, Miami

Even though Brown played in two fewer games than he did in 2005, he rushed for more yards and touchdowns last season. A broken wrist was the culprit for three missed contests, but the Dolphins have to like Brown?s future in the NFL. New coach Cam Cameron should take full advantage of his ability; although Brown may be no LaDainian Tomlinson, the former Chargers offensive coordinator will find ways to get him the ball.

Lassan says: What can Brown do for you? Well, let?s see: over 1,000 yards, and this should be the year he finally cracks the end zone a few more times. 2006 might?ve been a slight disappointment, but he?ll bounce back in 2007 and be a nice #2 running back for your roster.

Clinton Portis, Washington

Without a doubt, one of the biggest fantasy disappointments of 2006 was Portis. Injuries limited Portis to eight games and he rushed for a lackluster 523 yards and seven touchdowns ? a big dropoff from previous years. The biggest Redskin development wasn?t his injuries or struggles, but the emergence of Ladell Betts. Betts showed he can be a quality running back in this league, which may impact the amount of carries Portis will get.

Lassan says: It?s hard to argue with Portis? past success, and the fact is, he?s still young enough to be a 1,000-plus yard rusher every year. Betts will cut into his carries, but I think he?ll bounce back to a 1,200-yard level in 2007.

Cedric Benson, Chicago

The days of playing backup are over for Benson. The Bears traded Thomas Jones in the offseason and Benson is now the full-time starter. In two years in the league, Benson has totaled 919 rushing yards and six touchdowns, with the majority of his work coming last year. In his limited work, Benson has also impressed with a 4.1 yards per carry average.

Lassan says: Benson is a low risk/high reward type of pick. Some fantasy owners may not believe he can handle the full workload or just may not believe in Benson. Needless to say, Benson can be a real workhorse and a 1,000-plus yard rusher; he?s well worth a pick as a second running back for your roster.

Deuce McAllister, New Orleans

McAllister showed no ill effects from his knee injury of 2005, which caused him to missed eleven games. With Reggie Bush in the mix in the Saints backfield, McAllister will no longer tally 300 or more carries, but he can still be a fantasy factor. Even with Bush stealing time away, McAllister notched his fourth 1,000-yard season and totaled a nice ten touchdowns.

Lassan says: The second year off of a knee injury is always better, but McAllister may see a few more carries disappear with Bush and possibly a few from rookie Antonio Pittman. If you draft him, he?s a solid second back, but not a starter for your team.

Thomas Jones, New York Jets

Despite posting two 1,000-yard seasons in three years with the Bears, the team decided to give control of the running game to Cedric Benson. With Benson taking over the full time duties, Jones was shipped to New York, and he?ll be the Jets go-to back in 2007. Jones has posted two consecutive 1,000-yard years, as well as collecting solid catch totals the last two years, which should go up in New York.

Lassan says: The big concern with Jones is his touchdown numbers. He has never posted double digit numbers nor caught a receiving touchdown pass, and his career high rushing touchdown total is nine. Not a starter, but a nice second running back for your roster.

Marshawn Lynch, Buffalo

With Willis McGahee wearing out his welcome in Buffalo, the Bills drafted Lynch in the first round to take his spot and be an overall upgrade for the team. Lynch has good speed and hands, which makes him a good fit for their offense. Additionally, the Bills can ease the youngster into the lineup, as veteran Anthony Thomas can help ease the transition from college to the NFL.

Lassan says: Lynch is a great prospect for keeper leagues and he?ll eventually bump Thomas for the starting spot. It may take a game or two, but Lynch is definitely someone to keep your eye on in 2007.

Ahman Green, Houston

The Texans are hoping Green is the answer to their running game, but the veteran is 30 years old and health is a concern. Green hasn?t completed a full 16-game slate since 2003 and has watched his yards and touchdowns drop in every season since. Was moving from Green Bay to the Texans a real upgrade for the veteran running back? The jury is still out on that one.

Lassan says: In addition to Green?s concerns, the Texans are starting a quarterback with limited experience and the offensive line is still a question mark. Green is a seasoned vet, so he?ll eventually get it going, but he?s no longer a top 15 option. A second or third running back for your roster.

Marion Barber, Dallas

Barber didn?t get a starter?s workload, but he sure made his carries count. The second-year back tallied 135 carries last season, but reached paydirt 14 times. His 14 touchdowns ranked third among running backs last season. In his two years in the league, Barber has not carried a full load, and he?s only had one 100-yard performance. However, the Cowboys may look to give him more touches in 2007.

Lassan says: Consider Barber the more valuable of the two Cowboy running backs, especially with his goal line touches. If Barber becomes the starter, move him up the draft board.

Adrian Peterson, Minnesota

Peterson was an absolute workhorse at Oklahoma, but with Chester Taylor in the mix at Minnesota, the Vikings won?t ask the former Sooner to carry the entire workload. Peterson should share carries in his rookie year with Taylor, but there?s little doubt he could become the go-to guy before the season is done. The 6-2 back possesses great speed and power, but injury concerns with the Sooners have to raise a red flag in the NFL.

Lassan says: If you draft Peterson, you might want to grab Taylor. Handcuffing both backs would assure you get whichever back is the starter. Peterson is also a great keeper league option.

Chester Taylor, Minnesota

2006 was a real breakout season for Taylor. Although he had success with the Ravens, this was his first chance to be a starter in this league and he took full advantage of it. Taylor rushed for his first 1,000-yard season (1,216) and he posted a career high in rushing touchdowns and receptions. Although he had a strong season, Taylor seemed to wear down at the end of the year, which prompted the Vikings to take Adrian Peterson in the first round of the draft.

Lassan says: The Vikings haven?t forgotten about Taylor, but he?ll see a reduction in carries thanks to Peterson?s presence. If you draft one, draft the other and reap the benefits of whichever player ends up getting the bulk of the carries.

Jamal Lewis, Cleveland

How much life does Lewis have left in his legs? The Browns hope he?s got enough to carry the workload this year, and he?ll get plenty of carries ? the Browns are still trying to sort out their quarterback situation. Although Lewis hasn?t approached his 2003 form, he?s posted two 1,000-yard seasons in the last three years.

Lassan says: Lewis? yards per carry average has dropped precipitously, from 5.3 in 2003 to 3.6 last year. That?s usually not a good sign. It was somewhat puzzling that Lewis signed with the Browns ? after all, he?s usually done better playing against them. Consider Lewis a second or third running back for your roster, and he?ll need to prove he?s not too far on the decline.

Brandon Jacobs, New York Giants

Tiki Barber is on television, which means the Giants have a big hole in their backfield. Jacobs has been the goal-line specialist for the team in the last two years, but hasn?t carried the ball more than 96 times in a season. Despite his lack of carries, the Giants believe he?s ready for primetime, and he will assume the number one role for 2007.

Lassan says: The Giants need their running game to be strong and Jacobs has the talent to be the number one guy. However, he?s too much of an unknown to be drafted much higher than your second or third back. Jacobs will score, but who knows if he can put together the needed 100-yard performances to get into serious fantasy consideration.

Carnell Williams, Tampa Bay

When you rush for 1,178 yards in your rookie year, the expectations get even higher in year two. Unfortunately for Williams, he didn?t quite meet those lofty goals, and he finished with a sluggish 798 yards and one paltry touchdown. Needless to say, 2006 was a big disappointment for Williams and the Buccaneers overall. The team and fantasy owners can only help it was a slight bump in the road and not a sign of things to come.

Lassan says: Williams could play out as a high reward pick if he bounces back. However, be cautious with his value ? at least until he shows he is back to his 2005 level.

Warrick Dunn, Atlanta

Even though Dunn is one of the smaller running backs in the league, he?s been a model of consistency the past three years. Dunn has posted three consecutive 1,000-yard seasons, while rushing for 16 touchdowns during that time period. Additionally, he?s averaged 27 receptions per season. Although Dunn has been a great back for the Falcons, it would appear new coach Bobby Petrino will get away from their power running style, and second-year back Jerious Norwood will steal a few carries away.

Lassan says: Dunn is a likable guy, but realistically, he?s going to lose carries to Norwood. His age is working against him, but Dunn can still be a fantasy factor this year ? but only as a third or fourth running back for fantasy owners.

LenDale White, Tennessee

Travis Henry will be carrying the rock for Denver this year, so it means White gets his chance to be the Titans? number one back. This offseason hasn?t exactly gotten off to a great start for the second-year player, as he missed workouts and looked out of shape. White rushed for 244 yards in limited action last year and coaches like his upside, but weight concerns, as well as injuries have flooded his value with question marks.

Lassan says: Chris Brown and Chris Henry will battle for carries, and it?s no given White will win the starting job. If you draft White, you want to make sure you have plenty of other options or grab Brown and Henry as well.

Fred Taylor, Jacksonville

With the emergence of Maurice Jones-Drew, Taylor?s days of 1,000-yard seasons might be running a bit thin. Additionally, at 31 years old, Taylor isn?t getting any younger and the Jaguars will also see the return of power back Greg Jones into the lineup this season. Taylor posted his sixth 1,000-yard season last year, but clearly lost out on valuable carries to Jones-Drew, as he posted five rushing touchdowns.

Lassan says: Unless Jones-Drew gets hurt, consider Taylor a fantasy backup. Taylor will continue to lose carries and may have trouble reaching 1,000 yards in 2007.

Julius Jones, Dallas

Although Jones did most of the rushing and work between the 20s, Marion Barber got all the end zone touches ? which resulted in Jones rushing for only four touchdowns. His four touchdowns were the lowest in his career for a season, but he did post his first 1,000-yard season in his career. Although Jones caught 35 passes in 2005, he slumped to only nine last year.

Lassan says: As long as Barber gets the touchdown carries, Jones doesn?t hold much fantasy value. However, will things pan out like that once again? Some reports have indicated the Cowboys want to give Barber a bigger workload, which is a concern for Jones, but if things stay like last year ? they should balance out some. Monitor this battle very closely.

Kevin Jones, Detroit

Injuries killed a potential career year for Jones, and his Lisfranc injury is a concern going into the 2007 season. Not only is his foot a concern, the Lions also added former Bronco Tatum Bell into the mix, which is likely insurance in case Jones isn?t able to play at 100%. Whatever the case, there is little doubt Jones is a huge gamble this season. A new backfield mate and a major foot injury raises questions about whether he can repeat his 61-catch performance of 2007.

Lassan says: If Jones is healthy, he could rush for 1,000 yards and catch 70 passes, but that?s too much of a question mark. Worth a pick as a backup, but you might want to grab Bell as well.

Chris Henry, Tennessee

A guy named Chris Henry and Pacman Jones on the same roster? Oh, my. The Titans used their second round pick on Henry, who was a physical wonder at Arizona, but did little on the field. The Titans believe Henry will find his stride in the NFL, and that could be case. The youngster will have a chance to play right away, as the Titans continue to search for a dependable back to start. LenDale White hasn?t won any fans over in the coaching staff, while newly signed Chris Brown knows the system and runs hard when healthy.

Lassan says: Henry will compete for carries and should be a fantasy factor by the end of the year. Unless he can grab the starting job, he?s likely only a backup for your roster in 2007.

Tatum Bell, Detroit

Despite posting his first 1,000-yard season, Bell was shipped out of Denver to Detroit, and he?ll be battling Kevin Jones for carries ? assuming Jones is healthy. The Lions needed insurance for Jones? Lisfranc injury, and Bell is a solid rusher who has averaged 4.9 yards per carry in his career. The Lions will use their backs in the passing game, which means Bell will likely post career reception totals this season.

Lassan says: Bell?s got fantasy backup written all over him; with T.J. Duckett in the mix with the Lions, short-yardage touchdowns are probably out of the question. If Jones gets hurt and can?t play most of the year, grab Bell, but otherwise ? he?s likely a 600- or 700-yard rusher this year.

Jerious Norwood, Atlanta

It may not take too long for Norwood to grab the Falcons? top running back spot this year, so he?s definitely one to watch. Norwood rushed for 633 yards and two touchdowns in a backup role last season and he also posted a whopping 6.4 yards per carry average. Warrick Dunn is still the starter, but the Falcons will continue to give Norwood more carries, and if he continues to set a blistering six yards per carry average in 2007 he?ll be the starter by midseason.

Lassan says: Norwood has more upside than Dunn and is worth a look, depending on how soon he?ll grab the top spot. Dunn is still able to play at a high level, so he may hold off Norwood one more year, but he should top his total of 99 carries from 2006.

DeAngelo Williams, Carolina

The Panthers offense never got going last year, and out the door went offensive coordinator Dan Henning. Considering the Panthers vastly underachieved in 2006, they are going to make changes, and one of them is getting the ball in Williams? hands more. Although he?s only 5-9, Williams can get the tough yards between the tackles or bounce it outside for the big gain. His 501 yards last year are only a sign of things to come in 2007.

Lassan says: Deshaun Foster can?t stay healthy long enough to hold onto the starting spot, and Williams is the future for this team. Look for Williams to slowly chip away at the starting job, and he?ll eventually become the Panthers? number one guy.

Dominic Rhodes, Oakland

After winning a Super Bowl ring with the Colts, Rhodes has decided to move out west and take part in a rebuilding movement with the Raiders. The Colts didn?t really have much money under the cap, which made his decision a little easier. New Raider coach Lane Kiffin will likely use a backfield by committee approach, teaming Rhodes with LaMont Jordan.

Lassan says: Unless Rhodes gets all the carries, it?s hard to imagine him being much higher in the rankings. Rhodes could top his 641 rushing yards from last year, but don?t expect 1,000 yards.

Vernand Morency, Green Bay

With Ahman Green in Houston, the Packers are searching for a new number one back. Morency would appear to have the inside track on the job, but his hold on the job isn?t too strong. Morency has never carried the ball more than 91 times in a season, but last year saw him post a career high 421 rushing yards and 16 receptions.

Lassan says: Morency is still a young player and this will be only his fourth year in the league. The Packers will give Morency the first shot at winning the job, but rookie Brandon Jackson is going to be tough to keep off the field. If you draft Morency, handcuff him with Jackson.

Ladell Betts, Washington

Clinton Portis? injury was Betts big gain last year. With Portis limited to eight games, Betts rushed for 1,154 yards and four touchdowns, while catching 53 passes for 445 yards. Needless to say, Betts? strong season has opened up more carries for him in 2007, and the Redskins won?t be afraid to use him more this year.

Lassan says: Look for Betts to steal carries away from Portis, but he won?t top 1,000 yards again. If Portis suffers more injuries, then Betts would be a great starter for any fantasy roster.

Brandon Jackson, Green Bay

Jackson will battle with Vernand Morency for carries, as the Packers look to replace Ahman Green. Jackson was a second round pick and an early entry in the NFL Draft, which means he?s got a little room to grow. The Packers like Jackson?s receiving potential out of the backfield, as well as his cutback ability in the open field.

Lassan says: Morency may start out the 2007 season as the starter, but the Packers really like Jackson and he will likely end up the number one back. The Packers will slowly increase his repetitions and this is one battle to watch during the preseason.

Michael Turner, San Diego

The Chargers shopped Turner around before the NFL Draft, but they could not get what they considered fair value for him. Turner will again assume the role as LaDainian Tomlinson?s backup, but he holds a lot of potential for fantasy owners. If Tomlinson gets injured, the offense wouldn?t miss a beat with Turner and if the Chargers can?t sign him to a long-term deal, his value would go up with another team.

Lassan says: Turner could rush for 500-plus yards in a backup role, but his value is limited to just that this year. For keeper league purposes, another destination would increase his value.

Deshaun Foster, Carolina

If Foster could just stay healthy, he might be a consistent 1,000-yard rusher in the NFL. As it is, Foster has never played a full 16 game slate in his career and finds himself in a crowded backfield with DeAngelo Williams looking more and more like the starter. Foster has also never scored more than three rushing touchdowns in a season, but has posted back-to-back 30-plus catch seasons.

Lassan says: Foster and Williams will likely share carries throughout the year, so both backs are likely just backups for your roster. However, if either back can claim the job and stay healthy, they would be a nice fantasy player.

LaMont Jordan, Oakland

2006 was a complete disaster for the Raiders, and Jordan was one of the big disappointments. Coming off his first 1,000-yard season in his career and a monster 70-catch year, most fantasy owners were expecting another solid year. Unfortunately, 434 yards and two rushing touchdowns in nine games weren?t fantasy-worthy.

Lassan says: The Raiders signed Dominic Rhodes to help create a backfield by committee approach and Jordan?s value has been lowered as a result. Additionally, new coach Lane Kiffin wants to work in rookie Michael Bush some, which leaves Jordan?s value up in the air.

Leon Washington, New York Jets

As a team, the Jets struggled to run the ball, but found their best success when Washington was their feature back. In his rookie year, Washington rushed for 650 yards and four touchdowns, while catching 25 passes for 270 yards. With his strong rookie year, Washington topped the Jets in rushing yards and finished fourth in receptions.

Lassan says: Thomas Jones will be the unquestioned number one back, but Washington has proven he?s capable of being a solid number two. Don?t expect him to carry the ball 20 times a game, but he?s too valuable to keep on the bench and could be a great third down option for the offense.

Mike Bell, Denver

It was a surprise when Mike Shanahan named Bell his starting running back last season, but the undrafted back didn?t finish the year in the number one role. Bell finished the year with 677 yards and eight touchdowns, along with 20 receptions for 158 yards. However, he was a backup and his fantasy value was pretty minimal.

Lassan says: The Broncos always crank out great backs, so it will be no surprise when starter Travis Henry has a big year. If you select Bell this year, know his value is as a backup, but he?ll see around ten carries a game. If Henry has an injury, grab Bell immediately.

Najeh Davenport, Pittsburgh

Davenport was a late pickup for the Steelers, and he was brought in to fill the team?s need for a big back in the lineup. The former Packer was a solid backup to Willie Parker, as he totaled 221 yards and one touchdown on 60 carries. Although his numbers weren?t overly impressive, he filled a key role for the team.

Lassan says: The Steelers want to get Davenport more involved this season and the team needs a big back to emerge. Parker will get the bulk of the carries, but look for Davenport to be hitting closer to 400-500 yards this season.

Lorenzo Booker, Miami

With Ricky Williams out of the picture, the Dolphins? third round selection of Booker will pay big dividends. The Florida State product is a quick, shifty runner, while possessing great hands out of the backfield. The Dolphins can realistically expect him to make a big impact on third downs and it wouldn?t be surprising to see him to take a few carries away from Ronnie Brown. Booker could be a valuable home run threat.

Lassan says: Only a backup, but a ton of potential. Booker?s not really big enough to be an every down back, but if something happens to Brown, he will become the starter.

Reuben Droughns, New York Giants

The Browns decided to go in another direction at running back this offseason, so they shipped Droughns to the Giants. Although Droughns was the starter with the Browns, he?s likely only a second teamer in 2007. Brandon Jacobs has the number one spot locked down, but the team needed a solid insurance policy in case he struggles.

Lassan says: With Droughns you know what you are getting. He?s tough, runs hard and is a bull between the tackles. If Jacobs struggles, watch Droughns? carries very closely. The Giants know he?s capable of being a starter, so they won?t hesitate to bump his workload up.

Maurice Morris, Seattle

When Shaun Alexander went down with a foot injury, it was expected to be Morris? time to shine. Although Morris compiled 604 rushing yards last year, he didn?t really make much of impression while in the starting lineup. Additionally, he scored no rushing touchdowns and only has one in his five-year career.

Lassan says: The Seahawks had to be a little disappointed with Morris last year, but he?s still their backup. If Alexander goes down again, the team will turn to Morris, with what they hope will be better results. He?s not worth a roster spot in most leagues, but if you have Alexander, grab him for insurance.

Kevin Faulk, New England

The signing of Sammy Morris added another body to the Patriot backfield, which means Faulk?s value is somewhat up in the air. Over his career, Faulk has been a dependable player for the Patriots, mostly on the receiving end. Interestingly enough, Faulk has totaled 2,435 receiving yards in his career and 2398 rushing yards. Can you see where his value lies?

Lassan says: Expect Faulk to continue his third-down role in 2007, but it?s also possible he could get more carries with Corey Dillon out of the picture. Watch the Faulk-Morris battle for carries this season.

Tony Hunt, Philadelphia

Don?t expect Hunt to take over the Eagles starting duties anytime soon, but head coach Andy Reid likes his potential and big frame. Hunt was a tough runner at Penn State and with a roster full of smaller backs, the Eagles selected the former Nittany Lion to add a little punch to their ground game.

Lassan says: The Eagles backfield is a bit crowded at the moment; Correll Buckhalter, Ryan Moats and Brian Westbrook will all likely see carries, with Westbrook as the starter. Hunt will slowly work his way up the depth chart, but is probably in line for backup carries or the inactive list this year.

Michael Pittman, Tampa Bay

When Cadillac Williams was struggling last year, the calls for Pittman to get more carries were loud, but it didn?t matter. The Buccaneers struggled to get anything going offensively in 2006 and their running game ranked 28th in the league. Pittman?s value lies mostly with receptions, as he has 389 for 3,209 yards in his career.

Lassan says: Pittman is a quality backup, but he doesn?t have much value in terms of carries. He will provide solid reception totals, but the Buccaneers appear set with Williams taking the bulk of the work again.

Kenny Irons, Cincinnati

The second round pick of Kenny Irons clearly shows the Bengals were unhappy with Chris Perry and are prepared to move on. Kenny Irons doesn?t bring much to the table in terms of receptions, but he?s a tough runner and isn?t afraid to pickup the big yards inside. The Bengals will likely use him to spell Rudi Johnson and help keep him a little fresher in 2007.

Lassan says: Kenny Irons is a great keeper league pick, especially if he shows he can be the guy when Johnson steps aside. Kenny Watson or Perry will likely claim the third down role, but look for Kenny Irons to get less than ten carries per game.

Anthony Thomas, Buffalo

With the selection of Marshawn Lynch, the Bills are likely leaning towards Thomas being the top backup. Thomas can be an effective five- to 10-carry player, despite his wish to get a shot at the starting role. In a limited role last season, Thomas rushed for 378 yards and two touchdowns, while catching 22 passes.

Lassan says: Expect the Bills to keep Thomas in a similar role, with 100-150 carries this season, unless Lynch struggles. Thomas has two 1,000-yard seasons to his credit, but won?t equal those numbers in 2007.

Adrian Peterson, Chicago

Make sure you watch Peterson?s stock throughout the season. The trade of Thomas Jones to the Jets leaves the team without a dependable backup on the roster and Peterson will get five to ten carries per game in this role. Peterson has 622 rushing yards and five touchdowns in his five years in the league, but still needs to prove he?s a legitimate backup runner.

Lassan says: Don?t confuse this Adrian Peterson with Minnesota?s Adrian Peterson. So, with the Bears and Vikings in the same division, we will get to see Peterson versus Peterson twice a year. All jokes aside, Peterson is a number two back, but if something happens to Cedric Benson, pick him up.

Marcel Shipp, Arizona

Shipp is coming off his worst season in the NFL, but there is hope going into 2007. New Cardinals coach Ken Whisenhunt wants to get a little help for Edgerrin James, and Shipp is a valuable second back to have. Whisenhunt remembers the effect of a power running game from his days as Pittsburgh?s offensive coordinator, and he will look to get Shipp involved more to keep James fresh.

Lassan says: Don?t look for Shipp to repeat his dismal 47-yard performance of 2006. He?ll be valuable as a second back, but he won?t get any more than ten carries per game this year.

T.J. Duckett, Detroit

Offense is the name of the game in Detroit, and the Lions have added a few pieces in their backfield during the offseason. Starter Kevin Jones is hobbled by a foot injury, but Tatum Bell and Duckett were brought in as insurance. Duckett is coming off his worst season in the NFL, as he only mustered 132 yards in limited attempts with the Redskins.

Lassan says: Duckett can be an effective runner when called upon. However, he?s not much of a starter in this league. Look for the Lions to use him in short-yardage and on the goal line, but that?s probably it.

DeDe Dorsey, Indianapolis

What?s the buzz over a guy who hasn?t carried the ball in a NFL regular season game and went to college at Lindenwood? Simply, the Colts want to use two backs, and with the team deciding not to resign Dominic Rhodes, the door has opened up for Dorsey.

Lassan says: Assuming Dorsey wins the number two spot, he?s definitely worth a look as a backup on your roster ? especially when you consider the recent history of the Colts two back system. Joseph Addai will be the workhorse, but Dorsey will get involved with the offense, particularly on third downs.

Michael Bennett, Kansas City

If Larry Johnson holds out for a bigger contract, you have to upgrade Bennett?s value into the 30s. Johnson is the unquestioned starter for this team, but if he isn?t there, someone will get the carries. In either case, the Chiefs wanted to get Bennett more involved this year, and he should have no problem topping his 200 rushing yards last year.

Lassan says: Look for Bennett to push closer to the 100-carry mark this year, but draft pick Kolby Smith and Johnson?s status will determine how high or low he can go this year.

Sammy Morris, New England

Morris has pieced together a solid career and he?ll have a chance to win a Super Bowl ring with the Patriots. The big question with Morris is how much playing time he can expect to receive this year. Starting back Laurence Maroney is a top ten back, but he has an injured shoulder and Morris will be the go-to guy should he suffer any injury this season.

Lassan says: Look for Morris to be the top backup, but he?ll likely receive around 100 carries this year. Morris had 21 receptions last year and he could see that number rise, but Kevin Faulk is the Patriots top third down back at this point.

Musa Smith, Baltimore

Smith hasn?t carried the ball more than 36 times in a season, but the Ravens should look to give him a bigger workload in 2007. Mike Anderson is still with the team, but Smith will eventually become the team?s number two guy, thanks to his young legs. Additionally, Smith only had three less carries than Anderson last year, so there?s a lot of upside for this Georgia product.

Lassan says: Unless Willis McGahee gets hurt, Smith really doesn?t have much value. His value is mostly limited to injury replacement duty, unless the Ravens decide to give McGahee a few more breaks than they did with Lewis.

Correll Buckhalter, Philadelphia

Buckhalter?s career in the NFL has been marred by injuries, but he finally got on the field for the first time since 2003 last year. After spending two years on the sidelines, Buckhalter rebounded with a 345-yard and two touchdown season. Additionally, Buckhalter caught 24 passes for 256 yards and one touchdown in 2006.

Lassan says: If Brian Westbrook would suffer an injury, Buckhalter likely would claim the starting spot. However, he?s an injury risk and will still be the second back in 2007.

Michael Robinson, San Francisco

The former collegiate quarterback made a solid splash in the NFL last season. Robinson caught nine passes for 47 yards and carried the ball 38 times for 116 yards and two touchdowns. It was nothing special, but Robinson earned a spot in the Niner backfield rotation and could see more carries in 2007, as the team wants to keep Frank Gore fresh for a possible postseason berth.

Lassan says: Robinson won?t get enough carries to be a factor in most leagues, but if Gore gets hurt, he may be the guy that takes over as the number one ball carrier.

Ron Dayne, Houston

2006 might?ve been a career-saving move for Dayne. After posting 179 and 270 yards in 2004 and 2005, Dayne rebounded for 612 yards and five touchdowns with the Texans. It was his best rushing performance since posting 690 yards and seven touchdowns in 2001.

Lassan says: With the signing of Ahman Green, Dayne will see his workload reduced, but he will still be a factor. The Texans saw he can be effective at times, so he will spell Green, but not enough to be a fantasy option.

Noah Herron, Green Bay

Herron is the third Packer back to make an appearance in the rankings, and really, any of them could emerge as an option for fantasy owners. Herron emerged as a solid receiver for the team last season, as he nabbed 29 passes for 211 yards and two touchdowns. Herron only rushed for 150 yards, but with Ahman Green and Vernand Morency ahead of him, it was to be expected.

Lassan says: Herron probably won?t win the starting job, but he could be a valuable receiver for the team. Watch his snaps early in the season to see if he will be a factor in the passing game once again.

Mewelde Moore, Minnesota

With Chester Taylor and Adrian Peterson firmly entrenched as the Vikings starting running backs, don?t expect Moore to see many carries. Moore?s value with the Vikings is mostly as a punt returner, but he could see receptions as a third down back. Last year, Moore caught 46 passes for 468 yards and one touchdown.

Lassan says: Moore should be the Vikings third down back and punt returner, but he doesn?t have much value as a ball carrier. Worth a pick if you need receptions, but otherwise a waiver wire body.

Cedric Houston, New York Jets

The Jets struggled to get any consistency from their running backs early in the season, but when Leon Washington settled into the starting role, the others faded away ? except Houston. Although he started slowly, Houston finished the year on a high note, rushing for 11 or more attempts in the final six games he played in last year.

Lassan says: Although Houston gave the offense another back to throw into the mix, he had a few lackluster showings and is really the best fit as a third back. Houston will back up Thomas Jones and Washington this season, but could hit around 50-75 carries.

Brian Leonard, St. Louis

At Rutgers, Leonard played running back and fullback during his career, and the Rams hope to put that versatility to use in 2007. With Steven Jackson entrenched as the starter, don?t expect Leonard to get too many carries, but he could be a factor in the passing game. Leonard caught 38 passes for the Scarlet Knights last season.

Lassan says: The Rams do not have a capable backup for Jackson, and they need to spell him from time to time. Leonard is a nice choice, but he won?t get enough playing time to be a fantasy factor.

Justin Griffith, Oakland

Although few fullbacks find their way onto fantasy lists, Griffith is definitely one who is deserving of this consideration. Although he is moving from the power running game of Atlanta to a different scheme in Oakland, Griffith will still be a valuable receiver out of the backfield and could get a few touches on the goal-line.

Lassan says: Unless you play in a deep league or need a fullback for your roster, don?t draft Griffith. However, he?s reception totals are valuable for his position.

Mike Alstott, Tampa Bay

The days of Alstott approaching 600 rushing yards are over, but the bruising fullback still has some value. Alstott totaled 171 rushing yards and three touchdowns last season, while catching 21 passes for 85 yards. The Buccaneers are set on using Cadillac Williams and Michael Pittman, but Alstott could steal carries away around the goal line.

Lassan says: If the Buccaneers can develop offensive consistency, Alstott could be a nice goal line threat. At this point, the team doesn?t have enough offensive weapons or the consistent passing game to get Alstott enough chances.

Chris Perry, Cincinnati

When the Bengals selected Kenny Irons in the 2007 NFL Draft, Perry watched his playing time go up in smoke. Perry came to the team with a lot of potential and has yet to fulfill it. Perry caught 51 passes in 2005, but hasn?t played in a full season and has only 337 rushing yards to his credit.

Lassan says: Kenny Irons will likely takeover Perry?s role as the top backup to Rudi Johnson and Kenny Watson could be the team?s third down back. Perry will have to outduel Watson for time, and if he doesn?t, he could be searching for a new home.

Wali Lundy, Houston

A midseason stretch gave Lundy a chance at winning the starting job, but the Virginia product tallied only one 100-yard performance and didn?t do enough to hold off Ron Dayne. Lundy was basically relegated to third down or mop-up carries, as he watched his carries dwindle from 16 in Week 10 to one in Week 17.

Lassan says: Unless you are desperate, don?t worry about Lundy. Ahman Green and Ron Dayne will be more than adequate for the Texans, while Lundy could fill in in a third down role.

Jason Wright, Cleveland

Jamal Lewis is going to carry the rock about 20-30 times a game for the Browns in 2007, but Wright won?t have much value. The Browns offense is going to struggle to move the ball and Wright has only 226 rushing yards to his career credit. The Browns should work him in more third down packages, but he hasn?t done enough to warrant more snaps just yet.

Lassan says: If Lewis gets hurt, Wright may be a fringe option, but it?s hard to imagine him seeing more than 75 carries in 2007.

Michael Bush, Oakland

The Raiders drew high praise for their draft selections this season, and for good reason. Bush was the first pick on day two of the draft and is a high reward/low risk type of player. Bush was widely considered a top ten pick in the 2007 NFL Draft, before suffering a broken leg in the season opener against Kentucky.

Lassan says: The Raiders will ease Bush back into the workload, but his potential is enormous. Bush was a weapon inside the redzone at Louisville, and if he picks up where he left off, don?t be surprised to see him work his way into the rotation. A great keeper league option, cloudy value for 2007.

Antonio Pittman, New Orleans

Pittman?s selection by the Saints came as a surprise ? especially when you consider the team already has Reggie Bush and Deuce McAllister on the roster. Head coach Sean Payton just couldn?t resist adding another toy for his offense, and Pittman is quite a catch. The Ohio State product has great speed and could be another home run hitter for this offense.

Lassan says: Unless Bush or McAllister gets hurt, Pittman will have a hard time finding carries. However, some reports have indicated Pittman is in place to be the replacement for McAllister; just don?t bank on much this year.

Dwayne Wright, Buffalo

2007 could prove to be a great running back draft for the Bills. After taking Marshawn Lynch in the first round, the Bills grabbed Wright in the fourth round. Wright was a workhorse at Fresno State and rebounded after a knee injury kept him out of the 2005 season.

Lassan says: Anthony Thomas, Shaud Williams and Lynch all appear to be ahead of Wright on the depth chart, but don?t count this guy out. He?s got good size and is a tough runner ? something that could complement Lynch very well.

Maurice Hicks, San Francisco

Hicks has watched his carries slowly decrease in each of the last three seasons. In 2004, Hicks rushed 96 times, but fell to 59 in 2005 and 29 last season. Needless to say, the Niners haven?t exactly warmed to him as the team?s top backup, and Michael Robinson?s presence has only clouded his value even further.

Lassan says: Hicks and Robinson will compete for backup carries on the team and we like Robinson a tad more at this point.

Mike Anderson, Baltimore

Although Anderson has put together a solid career, his best years appear to be behind him. He?ll turn 34 during the season and didn?t get much work last season ? only 183 yards and one touchdown on 39 attempts. Anderson has ability to be a good short-term runner, but asking him to crank out another 1,000-yard season is probably out of the question.

Lassan says: Musa Smith and Anderson will compete for the second team role and both players could realistically hit right around the same amount of carries. Anderson is a good backup to have, but his fantasy value is minimal.

Kevan Barlow, Pittsburgh

Barlow was a late signing for the Steelers, and it?s all about backfield depth. Barlow played his college ball in Pittsburgh, so there is some familiarity with this signing. However, Barlow struggled to a 2.8 yards per carry average last season with the Jets and is probably no more than a rotation player.

Lassan says: Verron Haynes or Barlow will win the Steelers third running back spot and whichever player does will see carries. However, they won?t likely see more than 50 carries; even that might be a bit generous.
