Its not even just who Roy beat, but how he beat them... He dominated like nobody else, and he beat his opponents in every facet. ITs like why I know Floyd would beat Oscar before ever fighting a guy of Oscar's skill because, you can tell that these guys are doing things against good competition that we haven't seen before. Roy was making good competition look like a guy fighting in his first professional fight or some roadie trying to fight a champion... he made skilled guys look like amateurs.
