I'd be shocked if it's an issue that ever goes away entirely... I'm not talking about major stuff like robbery, but the minor stuff like alcohol issues and drug possession stuff. In fact, if the stuff didn't happen to some degree, I'd be concerned that it was being covered up. When you have a 100+ guys ages 18-22 in a college setting surrounded by beautiful ladies, alcohol o'plenty, and drugs galore, there's just no way around it. And it isn't an issue with just football players, it is a law of averages that engulfs the entire student body.
All that said, yes, it gets aggravating at times.
