For me, 9/11, it was my last year in college and I didn't know anything about Al Qaeda, I didn't know anything about bin Laden, I had no idea. I think probably after a few years when I started seeing how the country and the policy was shifting due to terrorism, I wanted to know: Why are these people terrorizing us, and who are they?

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.

You're never going to get rid of the injuries. The injuries are going to happen as long as there's football, especially the way it's always been played. So that's something that won't go away. But I guess they're trying to do the best they can to reduce those injuries and really take guys out of harm's way as much as they can.

Ever since I was a kid I've always loved history. I think that kind of catapulted things, but I would say the two major factors were maybe 9/11 and the election of Barack Obama.

I think that we do have a great country, but there's a lot of things that we're not so great at. Unfortunately, education is one of them.

I don't know what the NFL's going to look like in 15 years. Who knows. It's a great game; it's done a lot for me in my life.

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.
