1. Steven Jackson
Just 10 yards away from his eighth straight 1,000-yard rushing season, Jackson remains a work horse at the position.
However, he'll be 30 next season, and the carries are eventually going to catch up to him.
2. Reggie Bush
Bush needs 40 yards to accomplish back-to-back seasons with 1,000 rushing yards for the first time in his career, and few backs are as accomplished out of the backfield.
Despite being 28, Bush is still relatively young in terms of tough carries between the tackles.
3. Rashard Mendenhall
The former first-round pick has done little to help his price tag this season. Injuries have piled up, and a one-game suspension late might turn teams off.
However, he's still only 25, with 29 rushing touchdowns under his belt from 2009 to 2011.
4. Shonn Greene
After exploding onto the NFL scene during the 2010 playoffs, Greene has been mostly blah with the Jets. Big plays are few and far between for the 27-year-old.
5. Cedric Benson
Before suffering the dreaded Lisfranc injury in Week 5, Benson showed he can still contribute to a good offense. What he lacks in top-end speed, Benson makes up for in vision and savvy.
