I think this would have to explain his sudden three-pointers. That was his whole repertoire, once he was down to one leg.
It has to explain the defense, also. I just can't imagine playing basketball on one good leg, as a wing player/guard. As he said in the article, "It's hard when your 41-inch vertical is down to 20, and you see guys going over you for rebounds that shouldn't, and going past you that shouldn't." (rough quote from a tired man)
If anyone on the team next year feels that things are too hard, let them talk to Wes. Officially one of the toughest people that I have seen play.
