I think every year you're in the NFL you probably lose three or five years off your lifespan.

To me probably the biggest disappointments, as far as a football career goes, is I feel like I didn't live up to my potential, and I didn't win a Super Bowl ring.

Malcolm Gladwell was on TV talking about wanting to have college football banned. It's interesting just because of him even bringing the topic up. Sooner or later, whether people are for or against it whether they like it or not, that is going to be a discussion that is going to come up. That's how it all starts - someone brings up the inquiry: Should we continue to let our children play Pop Warner, high school, and college football? Ten, 15, 20 years from now, who knows where that conversation is going to be.

It's like, 'Wow. Yes, I had fun... but damn, was it really all worth it when I'm in a wheelchair at the age of 45 and can't play with my grandkids?'

I've never thought that I would see any man of color, not just a black president, but any man of color, I never thought that I would live to see that. I thought maybe my grandchildren would, but I never thought I would. So when Barack Obama first started to run I was like, "I've never heard of this guy - he probably doesn't have a shot." But then he started picking up steam and that piqued my interest.

I think whenever you go through something of that nature, you get to see who's really on your side and who's really there for you. That happened in my case. And it really let me understand that no matter how small of a decision you make, it's going to have a subsequent action or reaction, and something that started out very innocent turned into the tragedy that it was.

I'm not going to be the guy to be 36, 37 years old still trying to hang on and play in the NFL. I'll be 33 in a couple weeks, and there's a million things I want to do with my life before my time is up, which is hopefully 40, 50 years down the line from now at least. So I'd definitely be content.
