FSU has the talent, but they have definately underachieved the last few seasons. I think Miami peaked, I don't see them ever getting back to their glory days, their facilities are horrible, and since they joined the ACC, their quality of games, and thus national exposure has gone down. They would have been better off staying independent, like Notre Dame.
Miami was in the Big East for years. They bailed on the Big East in part for the money opportunities from a conference championship but also to reduce travel and for basketball I was told.
Miami consistantly was dominating the first round of the NFL up until last year. Coker was not getting the job done recruiting wise or with his coaching and was fired a year too late. They will be back.
