A closer look at first-round running backs taken in the NFL Draft since 2006
Adrian Peterson;OU;Minnesota;2007;No. 7
Arguably the best running back in the league, Peterson has rushed for at least 1,298 yards in each of his four seasons in the NFL. The four-time Pro Bowler is one of the league's brightest stars.
Chris Johnson;East Carolina;Tennessee;2008;No. 24
One of the most explosive players in the league, Johnson is a three-time Pro Bowl selection who has rushed for 4,598 yards in three NFL seasons.
DeAngelo Williams;Memphis;Carolina;2006;No. 27
Now a free agent, Williams has been a key member of the Panthers' attack alongside Jonathan Stewart. Has two 1,000-yard seasons and one Pro Bowl appearance during his five-year career.
Rashard Mendenhall;Illinois;Pittsburgh;2008;No. 23
Coming off back-to-back 1,000-yard seasons, Mendenhall is quickly becoming one of the top running backs in the NFL.
Reggie Bush;USC;New Orleans;2006;No. 2
A core member of the Saints' offensive attack, Bush can be electric at times and inconsistent at times. Injury struggles have hindered him throughout much of his career.
Joseph Addai;LSU;Indianapolis;2007;No. 30
A solid running back who has struggled with injuries after beginning his career with back-to-back 1,000-yard seasons.
Darren McFadden;Arkansas;Oakland;2008;No. 4
Struggled during his first two NFL seasons but rushed for 1,157 yards in 2010.
Jahvid Best;California;Detroit;2010;No. 30
Injury struggles hampered him after he burst onto the NFL landscape with five touchdowns in his first two NFL games. He accounted for 1,042 yards as a rookie.
Ryan Mathews;Fresno State;San Diego;2010;No. 12
Battled injuries but showed flashes of his ability as a rookie. He finished with 678 rushing yards in 2010.
Jonathan Stewart;Oregon;Carolina;2008;No. 13
Stewart has rushed for 2,739 yards in his three seasons in the NFL. He has joined Williams to be a solid 1-2 punch for Carolina since 2008.
Felix Jones;Arkansas;Dallas;2008;No. 22
The former Tulsa Washington standout has become one of the top playmakers for Dallas. He accounted for 1,250 yards (800 rushing, 450 receiving) in 2010.
Marshawn Lynch;California;Buffalo;2007;No. 12
Started his career with back-to-back 1,000-yard seasons but was traded to Seattle in 2010 and finished with 737 rushing yards.
Knowshon Moreno;Georgia;Denver;2009;No. 12
Moreno has been average during his first two seasons, rushing for 1,726 yards in 29 games.
C.J. Spiller;Clemson;Buffalo;2010;No. 9
His production as a rookie didn't match the production expected from a Top 10 NFL pick, but it's too early for him to be a bust. He finished with 283 rushing yards and 157 receiving yards.
Laurence Maroney;Minnesota;New England;2006;No. 21
Never really made a mark in the NFL. His future in the league is in doubt after a subpar 2010 with Denver.
Donald Brown;UConn;Indianapolis;2009;No. 27
It's a bit early for Brown to be called a disappointment, but he has rushed for just 778 yards on 207 carries in 24 NFL games.
Beanie Wells;Ohio State;Arizona;2009;No. 31
Wells had a solid rookie season with 793 yards in 2009, but took a step backward with 297 rushing yards in 13 games in 2010.
