There are some pretty unsavory things you could find in just about every program across the country. The NCAA isn't going to inflict the death penalty on a cash-cow program like Florida, or USC, or Nebraska or Notre Dame.
I wouldn't be surprised if there wasn't more to this story, though. There is no way Urban Meyer is under more stress than just about any D1 coach out there. Maybe he handles it differently and that's causing a problem, but bottom line is, it's a stressful job for everyone holding the HC title. I would bet there would be something for a good investigative reporter to find in this situation. Too bad there aren't many of them out there anymore.
