This is a full-contact sport. It's the objective to disable your opponent, even if sparring or a real fight. You've got to use your technique.

This level of competition is extremely high. Everybody is trained. Everybody has a game plan. Everybody has a nutritionist. Everybody has everything. It's here that you realize, as people, we're all equal.

I do believe that Brock Lesnar will be coming back. I don't want to call it from retirement, but he is a huge draw, big guy, sells tickets. So that's a fight I would be interested in.

As a fighter, you need to constantly improve. So that's what we've been doing: constantly improving striking, grappling, wrestling - there's always different aspects to improve.

I grew up in youth programs in Chicago, so they are definitely close to my heart. It is all about helping kids and giving back to a sport that has given me so much.

I tell them you have to be dedicated, have to decide if you want to be a serious basketball player or not. They always ask, 'What if you get discouraged?' You have to remember what your goal was in the first place.

If you spend a whole afternoon just eating popcorn and watching football, there's absolutely nothing wrong with that. But if that's all you do, you get swept along with the tide, without any idea of where you're going.

In football, it is a question sometimes of the mentality, understanding the players, the atmosphere, the confidence.
