USC and Alabama both tried to steal Riley away in his younger years. His coaching peers constantly described him as one of the best. I'll give you he never had the W-L record of an exceptional coach, but I'll trust the experts.
As I've said before, we just don't have enough evidence on Frost. He could be the next Chizik as easily as he could be the next Saban. He has almost zero experience as HC and he inherited a unique situation at UCF that may have inflated his success. I still think he is successful but I'm not going to spin the decision as a clear upgrade either. We ultimately took a chance on an unproven coach with one fantastic season because he played here.
It's not spin to say it's a clear upgrade because it absolutely is.
