My first inclination was that if something happens THAT immediately once you get there, it's probably not the fault of the place. But given that other football players were involved, maybe it was a case of them being bad influences on him? In which case, good for him.
And honestly BYU might be good for him. A guy who gets arrested for drugs less than two months into his college career is probably not on an ideal path and BYU could help with that
