As a Gator, I will say there is no comparison between FSU and Miami. FSU gets 80,000+ every home on their On-Campus football stadium, their facilities are top-notch. Miami has horrible facilities, and they play their games 30 miles away from Coral Gables to barely 30,000 per game. You would be nuts all things equal to choose Miami over FSU.
I never could figure out why those guys wanted to play for Spurrier. Urban Meyer? Sure, that was easy! But Spurrier was such a...jerk.
