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.

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.

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.

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.

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?

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?'
