Who said anything about excuses. If he wanted it more than his opponent he would have trained harder, he would have won, it's no surprise to BJ that his cardio is a problem if indeed that is the case. By saying "if BJ wants" simply means if he really wants it, it's attainable, he has the talent, he can do it..get it?
You should chill too.
Did you see Matts face, he looked far worse than BJ. Can't argue that, well maybe can.
