Fisher is an asshole. I pick him to win, but it wouldn't hurt my feelings to see Lauzon humble him.
Regarding the way Matt acted on TUF, he was sort of a . But I think he took offense at GSP avoiding him. I don't think he would have done that had GSP acted normal and hung around with the other trainers. GSP was being anti-social and Matt called him out on it. But I like GSP, and he is a good guy. Matt should have just let him be.
As far as Serra, what a hypocrite. Serra is guilty of everything he said about Matt, and more. At least Matt has the balls to say things to people's face. Serra acts nice to Rich and Matt while they are in front of him, and then badmouths them to everyone while they are away. It was funny how he freaked whenever he found out Charles McCarthy let Rich in on the fact that they were laughing at his advice.
