I can't speak for SC or VT, but I can say with almost certainty Nebraska is not interested. They just hired Mike Riley last year and the administration and majority of the fan base is happy with the direction the program is headed in. It's been a tough year record wise, but the team was in EVERY game and the Coach represented himself and the University very well. Nebraska fans may seem impatient from the outside looking in, but they're knowledgeable and can see enough positive change to give Riley more time. If Nebraska did make a move, Mark Richt, who was born in Omaha, would be a better fit.
From afar I like Miles. I don't know if he would be a fit at Nebraska. As entertaining and engaging as his is, the football purists would have a heart attack. Hell, some are still calling for a return to the triple option and leather helmets. Les does win and he does it the right way though. If I were to give any advice to LSU fans, I would simply say be careful what you wish for because you don't know what you'll get if a change is made. I wish we still had Frank Solich -- the program still hasn't recovered from that decision.
Les Miles would be a good fit at Nebraska. Ya'll like that 3 yards and a cloud of edible turf kind of thing.
