Come on guys. Do you ever pay attention to what other D 1 teams do with running backs these days? One guy simply cannot take the pounding week after week. You would be seriously placing them at risk of injury, or at least a downturn in effectiveness as the game goes along. Harbaugh (who I cannot stand, btw) uses 4 running backs regularly, just as one of many examples.
Akrum is a great running back, no doubt. But the argument that he does not get hit hard very often due to his skill set is just plain false. Watch a couple of games on your DVR and you will see the truth of the matter. The change up that teams we play have to face is a real strength for our run game. And, news flash, LeShun is one very fine running back. His speed is under rated (see long gains this year). I also noticed from re-watching Michigan vs Iowa and Nebr vs Iowa that later in the game, the defenses did not want anything to do with LeShun.
Full disclosure on my part: I do not believe that there are ulterior motives on the part of KF when it comes to determining who plays and how much. First, I have been around enough coaching staffs to know that position coaches make 99% of the decisions as to playing time. Second, yes, the head coach has veto power, but no head coach can watch each individual position on the depth chart and decide who should be playing. Finally, and this is indisputable: A head coach will make certain that the best players are on the field at all times, since as in business, the bottom line is profit, in football, the bottom line is winning.
We had better hope that next year, we have a back who can go along with Akrum at the same level we enjoyed with LeShun, or we are asking for trouble.
Come on. Guys who are quick don't get hit solid near as often as a power back does.
