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.

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?

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.

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 do know that there have been many Native people - I don't like to call them Native Americans, I guess, definitely not Indians - I've seen and read a lot about there's a big number of Natives that don't mind the Redskins name and they actually embrace it. Although there are a number of groups as well that are opposed to it.

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?'
