Perine beats up on easy competition. As a true freshman, that's still very impressive, but he's done nothing against good defenses.
25 carries for 87 yards against TCU
18 carries for 62 yards against Texas
24 carries for 89 yards against KSU
5 carries for 21 yards against Baylor
Ford would be much better against top competition if he could stay healthy and hold on to the ball. Unfortunately, I don't think he'll ever be able to do either, so we'll probably have to look in other directions.
I never thought I would say this, but Ross needs to get more carries. He was awful all the way through the Texas game, but he's been becoming our best RB as of late. He was our best RB against K-State, ISU, and Baylor. I want to beat teams like K-State and Baylor (and TCU). I'm not as interested in whooping up on teams like Kansas.
