Boxing is going to have to catch up with the kind of things UFC is doing. They're getting left behind.

I worked my ass off to earn what I have. You have to understand, not many people where I come from get to experience this kind of life.

It is the most powerful submission in the sport. It is a beautiful thing. You're holding them into you, their back is on you, and you are basically choking them gradually like a boa constrictor and once you've got them, the pressure goes on and they have to submit or they are going to stop breathing. It happened to me early in my career, and I panicked, and gave in, I tapped out too early. I learned a lot from that. I learned from it, learned how to do the move better, learned how to avoid it being done to me.

Golf isn't a sport, it's a game. I'm not saying it's not a difficult game, with lots of mental stuff. But it's not a sport like mine. Where is the combat, the intensity of what we do?

A fight is mental, not just physical and psychological warfare is absolutely part of that.

I don't watch the news, I don't care about politics, I don't care about other sports.

I don't believe in talent. Talent doesn't exist.
