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.

I don't have to put on shoulder pads and run out there and let somebody hit on me a little bit.

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

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.

Don't complain to others about your troubles. Half of them don't care and the other half are glad.

If you're not settled spiritually, things can be a little bit more chaotic than normal.

Football is a team sport, and there is no one individual who is bigger than the next person.
