I've heard someone else mention the Georgia defensive coordinator. I'd also love to see him become the coach. He's probably right below Smart and Narduzzi in my mind and he's a young guy. Secondary coach at Alabama for two national championships, Florida State's defensive coordinator for their championship win, and now the coordinator for a good SEC team. I think he'd command a big salary, because I guarantee there are some southern teams wanting him.
He's only 40 and he has familiarity with Nuss. I think he'd keep Nuss on board, which I'd like to see. Bring in a new RB coach(steal Georgia's coach please), a new o-line coach, a new defensive coodinator, and he would run a similar style to Michigans.

The only problem I have at all with hiring him is in 5 years, when he's been successful, I could easily see him leaving for an SEC or successful southern school. Saban will begin looking at retiring by then and who knows how long people in Georgia are going to put up with Richt. I think Michigan has the money and resources to keep him though. If he is successful, I think he will want to stick with the program he has helped rebuild. Especially since Michigan can offer him the resources and money that anyone else could.

Pruitt makes a lot of sense to me. I'd rather Michigan take Pruitt and keep Nuss since they have worked together. If I'm Michigan, I offer Pruitt a 5 year, 25-30 million deal. Money isn't an issue and it seems like Pruitt is fine with moving around. He should at least be good at recruiting with all his championships, Peppers would love him, he's familiar with Nuss, and he has a load of southern ties. He is also young and someone is going to get a fantastic coach in him.
