I was going to ask why he'd even want to sit there but that actually makes sense ... Next thing though, if he's really not disrespectful, he wears something neutral to the game ...and if he doesn't think of it on his own, you should "suggest" it to him.
Probably would be a good idea, but honestly. If I'm going to a USF game, I'm wearing a USF shirt. Even if I'm sitting in someone else's student section. So, it's up to him, I'll probably joke around and say he should just wear a black shirt so he doesn't get jumped but I'm pretty sure he's gonna wear an FSU shirt.
I will most likely throw something on him..... Twice
