I disagree Pacman wouldnt fall over after the 1st one, Pacs speed would cause Oscar a few problems imo, 50:50 fight. However i believe Oscar had the jab and size to really take it to Mayweather and win a UD. Mosley had the speed, power and size to really rival Pacquiao, what a fight that would have been, Mosley KO. However due to Mosley's non existent jab he would struggle to pin down a target like Mayweather and would lose a close decision.
Outlanding someone 2-1 is not barely beating them and Oscar technically is pretty poor in this fight and much more defensively open, he improved his technical skills after this
