Quinton Jackson is a pretty easygoing, fun loving dude unless you count his mental meltdown last July in Southern California. That incident and the weeks that followed are still part of the guy's make-up. He believes that he needed to make some changes, mature and deal with anger in a better way. Jackson is putting himself through the ringer as he tries to co-exist on The Ultimate Fighter 10 with Rashad Evans:

"It's an exercise for me to control my temper. That's why I make jokes to keep myself happy so I can be in a good mood," Jackson said. Evans just rubs him the wrong way. "Some of things he says just trigger some thoughts in my mind. I just don't like those thoughts. I don't know if I'll go to jail. Two professional fighters fight on the show ... can I go to jail for that?"

Jackson was joking when he made the jail comment but he was serious that since their face-to-face showdown in the Octagon at UFC 96, he can't stand Evans. He's a little worried about potentially ruining the show:

"This is the biggest test if I can keep from attacking Rashad Evans on the show. I don't know if I'll want to do the show anymore. I just don't trust my temper like that. I'm going to try to be a professional so the show can go on. If I get mad at him and lose my temper, I don't know if I'll want to come back."

Jackson made his own bed and now he has to lie in it. He chose to spend six weeks around Evans with the coaching slot on TUF 10 over facing UFC light heavyweight champ Lyoto Machida. He eventually gets a fight with Evans if he can make it through the season in one piece.

I don't think the UFC regrets putting Jackson on the show but it will if he goes off the deep end again. It's an interesting decision to include a guy who is less than a year removed from a mental breakdown that landed him in jail and hospital isolation. But it's not the first time a person walking that fine line has been on reality television and it certainly won't be the last.
