Player safety is definitely something that has to be at the top of the list. I think that the union and the NFL are doing all they can to make sure they're protecting the players the best they can.

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?'

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?

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.

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.

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.
