I love the sport but it's definitely taken a toll on me. The first two years after I retired I was in pain and couldn't even sit in a chair for 2 years. 2 years! You want a sport that takes care of you the way you take care of the sport.

In the NFL they talk about "contracts," but it's not really a contract, it's a one year agreement. If you have a 10 year contract, it means nothing. If you get cut in the NFL, you get nothing. People don't talk about that.

Life isn't about a hand-out. That's not what the NFL is about and that won't get you in the NFL or take care of you once you're out of the NFL. You have to work.

I love being single. I can come and go as I please and stay out as late as I want to.

When I loved it, I loved it. It was nothing better.

I run upright mostly when I see daylight, so if you watch film you'll see I don't get hit in the chest much.

In the NFL, you have a short shelf life. As a running back, if you're the first pick, and you're NFL life expectancy is only 3.5-6 years, your first big contract might not come until three years in - well, you might never get there. They need to get those signing bonuses up front because nothing is guaranteed.
