As a pro athlete, your body is your tool

I remember reading once that running backs in the NFL last for less than three seasons. Their bodies simply can't take the incredible pounding.

So how does Jets Coach Eric Mangini explain that NYJ RB Thomas Jones has played for nine seasons, carrying the ball almost 1900 times over 130 games?

"Thomas is really outstanding in the way that he takes care of his body. That's your tool. That's what you need to have to execute your craft. He does it diligently."
