If I'm tired, I'm coming out. I won't do that to my teammates and stay on the field when I know I'm not going to be able to do it.

I didn't think of football growing up. This wasn't my career, something I chose. It was something I was picked in.

Every year you've got somebody coming in and trying to kick you off, so you have to prove yourself. Even for the coaches, too. Their jobs are always on the line.

Growing up, as a kid, my father was always there.

Football's about winning and I'm a winner, but you also have to set standards and entertain people.

The way skateboarding contests were in the past was like going to a basketball game and being told at the end of the game what the score was and who won. Think about how unengaging that would be if you didn't know who was ahead or if it was a close game.

Basketball is basketball, but with each level, there's new challenges and new things you have to pick up.
