My career has been defined by dominating every opportunity presented to me. I am excited for my newest opportunity representing WWE 2K17 as the franchise's ambassador and honoured to serve as the WWE 2K17 cover Superstar.

At the top of my career, I wasn't at the top of my game.

My hands. I'm constantly working on my hands. I'm constantly working on my ground game and constantly trying not to get satisfied with where I'm at with my career and where I'm at as an athlete. I'm somewhat happy, but never satisfied.

I felt like I was cheated out of my career in the UFC. In my mind and in my heart, I never lost to a foe. I never lost to an opponent. I lost to diverticulitis. That was my opponent that beat me. A lot of other people might have other thoughts about that.

When you are a footballer, you eat, sleep, and breathe football. If I have a bad training session, I can go home and do whatever I want, but you still feel an emptiness.

Whether I'd stopped playing professionally at 17 - or if I stop at 35 - tennis will always be a part of my life.

The most important thing you learn as a sports photographer is anticipation - not where the action is taking place, but where it's going to take place. Not where the subject is now, but where they're going to be.

I had grown up during a time when Notre Dame football was held in the highest esteem. I listened to all of the games on the radio.
