Rate Wilfredo Vazquez Sr. superbantam weight reign. 10 successful title defenses, six by KO. Of course he was previously bantam weight champ and afterwards became featherweight champ with six title defenses until he lost to Naseem Hamed (by that time he was way past his prime). But at superbantam was were he stayed longer.
Yeah, but REED, the people who know boxing (like most dudes here) know damn well that Mayweather was THE GUY, he fought and beat the best... Joey Maxim held the 175 pound titel, Ezzard Charles never did, but Ezzard Charles was one of the greatest fighters of all time and Maxim was basically a good fighter
