I'm too lazy to look and see if anybody posted the video of the guy who sparred with Floyd, Manny and Mosley, and Margarito and was on board with that comment.
Mosley is a stronger puncher but Pacquiao can land better shots than those two that Mosley landed. Any natural WW will be a stronger puncher than Pacquiao who with his frame is a JrWW at best. Even Cotto was a stronger puncher than Pacquiao but boxing is not all about punching strength.
Ever since he KO'd Hatton, Pac was now the big puncher. You gotta throw that one out. Hatton never saw the punch at all and led with his face. He hasnt cold-cocked anyone else, recently anyway. And his sparring partner never rated him higher than Mosley, Margo, or PBF in punching power. Thats the only way to really tell is to go trde punches with him.
If we take that guy's word for it punching power from strongest to weakest goes Mosley > margariTOE > Cotto > Floyd > emmanuel dapidran pacquiao [ame]http://www.youtube.com/watch?v=QqJqm94pJBA[/ame] I always thought Cotto hits harder than marg and emmanuel hits harder than Floyd.:think
mosley. mosley can hurt WW w/ one good punch, while pac needed combinations to hurt his opponent (especially at WW). if mosley was the one who threw that uppercut that landed on cotto's chin at round 4, it'll be lights out for miguel.
makes sense. Mosley and Margo are big WWs who can easily fight at 154. Cotto and Mayweather are average sized WW's Pac is a blown up JWW at best.
