but potential is set in stone in real life...players either reach it, exceed it, or don't reach it. If player's can't play above their potential at all well that's one thing....but a player's potential never really changes. You either have the potential to be great or you don't. I don't think that because Darren McFadden had a mediocre season that all of a sudden people are saying "wow...he just can't do it." There's a lot of "ifs" in sports, IF he stays healthy and IF he has the drive then he can do it. His potential never changes...it's just up to him to deliver.
