Ok, I will try to Explain this the best i can. Look at all the fighters that fought Hughes, and hughes beat. which are very good fighters.
Do you think those same fighters if they fight GSP would Be Beaten by GSP (other then Penn). Not saying GSP isn't a Great fighter by far.
Hey chiclets,
I think if BJ trained cardio the way he would need to in order to dominate at WW, he wouldn't be heavy enough to compete at WW. The guy is a beast, technical, flexible, and tough, and may win at WW, even fighting under that weight, but the cardio may make him too light to compete. I could be wrong though. JKB
