Mark Martin? You serious?
That old Duffer? He will need someone to pull the walker away from his car after he climbs in. In fact I heard his is the only Nascar that has a family sedan type door to get in cause he can't climb in the window.
Ok, all kidding aside I am thinking Carl Edwards. He was dominant last year at the end of the season and was winning everything but just could not close the gap of points in the chase. So with that.... Carl Edwards. Thats my pick.
