If you have a Reggie Bush level offensive talent you play him on offense. The disparity between him and every other skill player for UM since Denard is insane. We can plug in an adequate replacement at nickel, but we have nobody close to Peppers at RB and the QB and RB positions are the two most important in college. Having an all American level RB is wayyyy more important than at DB. If we want to be beat OSU it's with Peppers full time on offense.
