Your biggest fear is the transition from football to business. You feel inferior at the beginning. You don't have the knowledge to compete. But once you start focusing and understanding, then you start relating to things.

There's a lot of dancing in football. You can see Victor Cruz doing a little bit of a cha-cha or samba move in the end zone. You can see Terrell Owens getting his popcorn ready. You can see Ochocinco doing the Riverdance. But not so much when it comes to ballroom.

I'm very confident I'm one of the best to ever play the game, but once you talk about the greatest, how can you define greatest?

Adrian Peterson is redefining the way teams defend the running ability.

A lot of the issues of the Dallas Cowboys yesterday having pressure on Tony Romo, came from the outside pressure.

As a former football player who has carried a football more than 4,000 times, trust me, I did not go into ballroom dancing with my body being 100 percent, with no aches or pains or ailments coming with me. When you're dancing, you're doing stuff that your body's not used to, and so you start to aggravate those old injuries.

Some if it may seem hokey to some people, but if you traveled where I've traveled, done what I've done and seen the results that I've been getting, then you understand where I'm coming from. Playing in a football game is like being in 30-40 car accidents. You can find yourself in awkward positions. That stuff takes its toll. But if you take advantage of health care, balance your body back out, put it back where its supposed to be, you function better, and you recover faster.
