I know it sounds like i'm trying to bash the guy, I have not seen one thing that says he can carry the ball as the primary runner.
Check out his stats during "The Run to the Playoff". the only game he averaged 4 yards per carry was the philly game and that was because he had more than half his yards on one play. He runs too high, he gets hit too hard and he fumbles too often.
