someone on here by the name of divac i believe mentioned something earlier that i've always known but never really put any thought into until now.. mayweather-maidana 2 is the only championship fight in his career that sparks my interest because in that fight he defended his 154 BELT at 147....... not only did he defend his light middleweight belt at welterweight, he was also defending his welterweight belt as well. to clarify to any individuals who don't understand: he defended two separate belts from two separate classes. that's rid!ckulous
