I hate that Sam didn't loosen up and enjoy himself. The word that I heard is that he was really loose in the locker room but the guys just wouldn't allow him to fit in.
Sometimes you just have to take it like a man and I'm not sure Sam did that. Maybe he was too vocal in the locker room when the guys were trying to help him fit in.
I wouldn't be surprised to see him pop up somewhere else and force himself into a wide receiver. He looks like he'd handle a position change and be receptive to that. Based on his past, I don't think he'd be a very good tight end, although he has the frame for it.
If he could just go straight into the Arena League, there may be a place for him there.
