Here are some excellent backs who could run for 2,000 yards if not hampered by some major issue whether it be the system they play in, their own explosiveness, and/or sharing carries.
Alfred Morris, FAU- Powerful back in a defensively weak conference. Unfortunately, not very explosive so will not have the yards per carry to equal 2,000.
Montel Harris, Boston College- Thickly built back who can really grind a game out. Will get his carries but is not a breakaway threat so will not get a lot of yards for his carries. One thing to keep in mind is him running out of the Wildcat formation. Also plays in the defensively stout ACC.
Daniel Thomas, Kansas State- Tall, powerful back built a lot like John Clay. Unlike Clay, does not have much talent around him.
Robert Turbin- Before tearing his ACL, Turbin was one of my favorite backs going into 2010. He has a good build, can catch the ball, has good speed, and reminds me a bit of a poor man's Ryan Williams. Although he does have to split carries with his quarterback.
Evan Royster- Another tall, lean back who is as complete a back as you will find. However, he plays in a defensive tough conference, is breaking in a new quarterback, and does not receive the amount of carries necessary to reach 2,000 yards.
Jacquizz Rodgers- Rodgers really could break 2,000 yards but I am concerned about his size. I bite my tongue as I say it because of guys like Garrett Wolfe and Darren Sproles but he is taking a beating every year in the Pac-10. Also his team has a new quarterback.
Noel Devine- As explosive as they come, Devine is a homerun threat everytime he touches the pigskin. However, his carries are limited due in part to his size and his system. He will also be working with a new quarterback and will lose some carries to Ryan Clarke.
Vai Taua- Big back who is really explosive. Will share carries with Colin Kaepernick and Lampford Mark.
Kendall Hunter- Great year two years ago but now has a new OC and has some size/injury issues.
Ryan Williams- Powerful, fast, and complete back who could very well vie for 2,000 yards if not for Tyrod Taylor, Darren Evans, and David Wilson stealing carries.
Mark Ingram- Heisman winning back who has a dangerous skill set. Unfortunately has a new quarterback and will be sharing carries with Trent Richardson. Also plays in the tough SEC.
LaMichael James- Possibly the most explosive back in college football but due to the system he plays in, he will lose carries to his quarterback, Jeremiah Masoli. Also his eligibility is in question for 2010.
