I have never been to one of Wes's fights, but has he always been poor on cardio? I just can't understand how somebody gets that kind of opportunity and does not have himself in the best shape of his life? I think you are right that if he was in decent cardio shape, he would have ended it without letting the judges screw him.
At the end of the day, he did get screwed by the judges. But I guess that is what happens when you face the other teams number 1 draft pick.
