It's funny, I boycott his fights because I don't think anyplace that makes even a pretense out of drug testing should hire him, but as a person, I like the guy, I like hearing what he has to say. Basically, I'm good with him except where it comes to fighting. I don't even know when he had his last fight. I thought he was retired.
Edit: The other option I haven't seen mentioned is Vitor Belfort. There are a lot of people that want to see TRT Vitor fight again (not me,) so I think it's between these two guys.
