I think the biggest hire they should be concerned with is a new AD. If they don't get rid of that clown they are doomed. The problem is this dude has the biggest ego and couldn't take a back seat to bringing in a premier coach. RR was bad, but honestly who is Brady Hoke?
I know folks are throwing around the Harbaugh's, but if you were in their situations why would you want to come back to College ball (money aside) and have to deal with all the rules and parents and and the NCAA (pardon my french, who are the biggest fucking joke in the history of sport)?
