You can look at everything from pre-Heisman to post-Heisman, and I think that’s why it ranks up at the top, because before then, I didn’t even think I was good enough to be a professional ballplayer.

I just felt like I had run out of steam. I just felt like it was my time.

Individual goals never meant that much to me. The Heisman is no exception.

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?

A lot of times I did lose yards on a run, but it wasn't for lack of trying.

Let's just win it and go home.

It was a wonderful experience to play in the NFL, and I have no regrets. I truly will miss playing for the Lions. I consider the Lions' players, coaches, staff, management and fans my family. I leave on good terms with everyone in the organization.
