As a kid, I played my share of football in the street or in a vacant lot.

I didn't know exactly what I wanted to do in school, but I definitely didn't have adequate time to reach my full potential as a student.

I don’t want to get too detailed into it, but when you’re a good high school running back, you can almost be whatever type of runner you want to be. If you’re a good size and a good athlete, you can be whatever type of runner you want.

I'm from Kansas, so there were a lot of vacant lots and open fields to tackle each other in so we could avoid tackling each other on the street. But running on the street and trying not to get taken down on the concrete, that will make you fast, that's for sure.

In all the time that people have known me, has anyone ever heard me talk about the importance of rushing records or finishing with the most touchdowns? So if that's never been important to me, then why would that be a motivation to keep playing?

If I could start with anybody, I would initially draft Tom Brady. Then I would go get Ray Lewis, and then maybe an offensive lineman, or somebody like Adrian Peterson.

I quit because I didnt feel like the Detroit Lions had a chance to win. It just killed my enjoyment of the game.
