With football training camps underway, Onion Sports is preparing fans for the upcoming 2013 NFL season by ranking players at every position. Here’s a helpful guide to the league’s best running backs.

10. DeMarco Murray: Onion Sports felt obligated to put a player from the Cowboys on this list so whiny fans in Dallas will stop complaining

9. Reggie Bush: Has all the good qualities you look for in a running back and yet, alas, how true that many perfect parts may form an imperfect, unsettling whole

8. Michael Vick: The talented Philadelphia tailback is expected to utilize some trick throwing plays in Chip Kelly’s new offense

7. Frank Gore: Coming off a season in which he racked up 259 carries for 1,212 yards, Gore seems poised to rack up 259 carries for 1,212 yards

6. Maurice Jones-Drew: Dominates the backfield with a mixture of athleticism and explosive speed that he hopes will be enough to help him break free from any contract

5. C.J. Spiller: In prime position to ride Kevin Kolb’s futility all season long

4. Trent Richardson: After an impressive rookie season for the Browns, don’t be surprised if this year he breaks out for over 1,000 completely wasted yards

3. Ray Rice: Quick feet and small stature should allow him to blow through the new vacancies in the Ravens’ offensive line

2. Arian Foster: Tough running back who proved doubters wrong that he wasn’t durable enough to handle the punishing disappointment of playing for the Texans

1. Adrian Peterson: Stiff-arm has dramatically improved since he began using the hand not carrying the ball
