See what Choz said on this topic a few days ago, Red and xhoops.
Also see all the threads where posters ask the question, who is the last coach to come in to Div 1 with NO coaching experience at all - let alone high Division 1. There is a lot to being a head coach of a college team.
There's no history of this. He hasn't coached. To me, there would be too much at stake to trust the program to a complete neophyte. If he'd coached ANYWHERE - done some aspect of the work of coaching, even on an assistant level, maybe.
