Mayweather is a welterweight now so when he fights anybody that are not welterweight that is considered fighting smaller men. pac started at 106-107 lbs and now he is a jr welterweight. If he fights chris john or israel vaquez wouldn't you consider that fighting smaller men? :smoke
By your logic. Mosley fought at 154, then came down to 147 and beat margarito for the title. he should get no credit becasue he fought smaller man. He should of kept fighting junior middleweights. is that the position u wanna take?
