But Mayweather is already climbing the p4p all time list... the thing is, Mayweather by Pacquaio's age was fighting at 140-147 while Pacquaio is still at 130 which Mayweather last fight at that weight was 24 when he fought Jesus Chavez. The difference is he went up at least at lightweight at beat Castillo who would beat any of the current lightweights at this point in their careers with ease when he was at his best during that time period. Regardless Hatton is a good if not great fighter for this generation and if Pacquaio beats him, he definitely goes up as one of the best featherweights and superfeatherweights to ever fight. Already I think he would do well with some of the best.
