So I guess what you are saying is that Willis, Roscoe, and Kevin are thugs because you have the perception that all UM players are thugs.
Your perception that they are thugs is premised on "contract disputes," "drug use," "rap sheets", and "sex."
You just described every major college football program.
Oh, and by the way, if you went to college (any college), you may have noticed that there was some sex and drug use.
Your post is kind of like saying that the Bills are made up of a bunch of murderers and child molesters because OJ and TH once played for the Bills.
