Sheldon talks about being a locker room leader in this article, acting out against the team, and about being a professional.
"I'm the leader on the football team, and it's bad for players to see me in a situation where I'm not happy. But I'm not going to blow up the NovaCare Complex. I'm not going to be one of the guys who puts on a show week in and week out when the media comes to my locker."
Glad to hear he doesn't plan on using any explosives during camp and he won't be complaining to the media every chance he gets, well, minus telling the media that he is unhappy but not going to tell the media when they talk to him again.
