Moving up in weight classes and winning is impressive but not not as impressive if you do not fight the best in the weight class and that is why I can't have Floyd as number 1. Cas,Tszyu,Hatton,Cotto,etc etc these are big names he just glossed over for whatever reason. I'd be far far more impressed if he stayed at a weight class for a while and cleaned up,imagine him fighting the monsters at 147?! No that would be some legacy! (That's just my opinion but running through weight classes beating Gatti,Brusseles etc is hardly amazing is it>)
