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

I want to thank all of the fans and media who made playing in the NFL such a wonderful experience. I have had the pleasure of meeting many of them.

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.

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.

Christianity affects your whole life. I feel I'm more competitive, a better player, but off the field is where there is always a battle.

Happiness does not come from football awards. It's terrible to correlate happiness with football. Happiness comes from a good job, being able to feed your wife and kids. I don't dream football, I dream the American dream - two cars in a garage, be a happy father.

My desire to exit the game is greater than my desire to remain in it. I have searched my heart through and through and feel comfortable with this decision.
