Howard Schnellenbarger started all of the dirty stuff at Miami.
Jimmy Johnson embraced it and took it to the next level, such as all of that Pell Grant fraud, as well as encouraging the thug culture.
Dennis Erickson maintained the status quo, as the nickname of "Convicts" came to the forefront. Having the 2 Live Crew as their cheerleaders didn't help the image either, especially when Luther Campbell was putting cash bounties on Irish players.
Erickson cowardly left for the Seahawks, since he knew the investigations were finally coming, and Butch Davis was left holding the bag.
Davis actually rebuilt Miami better, and cleaner, until that scumbag Larry Coker came around.
