Mayweather fought them in his weight class, Pacman fought them in their weight classes. Pacman climbed up the weight classes to fight Barrera, Morales, etc.
Pacquiao's willing to fight the best and that's what has gotten him to the top of the sport in big fights.
who else is going to respond their nonsense? this is a place where they cant get shooed away or made to shut up.
i love pacman and he's great for the sport. i think his best weight is 140. he's fast and strong, and his legs seem great. not at all too much weight. i also think 140 is mayweathers best weight. he's not a huge puncher, and he seems small next to cotto or williams. regaurdless of what weight the careers of these guys started at. i think they are both best at 140. a great fight and an even match. if the fight happens, no excuses.
Pacquiao is just such a great fighter that he is beating up other bigger great fighter. The guy have been moving up so many weight classes and he is still rolling.
