I agree he is doing well, but he's also at Liberty. If he were such a hot commodity why is his name not on any list when big schools are going through change? You run the risk of players and parents not buying what he is selling after his issues. I think he's a pretty good coach, but his personality and affinity for not telling the truth hurt him.
Huskers just had a coach per all accounts abused his power and that is exactly what Freeze did at Ole Miss. He thought he was above it all. That he could do anything he wanted to do (There were lots of rumors of cheating, too). I see no reason why the Huskers would want a take a gamble on another coach who has been involved in a scandal?
