Off the top of my head, Mayweather has: Castillo x 2, Corrales, Judah, Hatton, Marquez, Gatti, Mosley and De La Hoya. Manny has: Morales x 2, Barrera x 2, Marquez, Hatton, Cotto, Clottey and De La Hoya.
if you consider the fighter in the prime condition, unbeaten, what weight class they fought in, its close.
Sitting on the fence, like me. You're right though, its very close. For instance how would you seperate Manny destruction of Cotto, and Mayweather's dominance of Mosley..
Put Hernandez in the list too, another top fighter Floyd went through I say Mayweather for two reasons. A: He's never lost to anyone. B: He's beaten more undefeated fighters. C: He avenged his "close" fight with JLC - something Pacquaio never did with JMM who should have had one (or both) of the decisions in their fights. Undefeated counts in a resume.
Cotto was 28 when he fought Pac and not nearly as far gone as Mosley. In fact aside from a bad loss to Margarito you can't really say he's far removed from his prime.
What he said! Plus I like PBF win over Oscars win more than Mannys even though the fight was closer, as PBF went up to Oscars weight and Oscar had all the advantages and was not weight drained to a weight he hadnt been in for 7 yrs! Plus May was the first person to take away hattons 0. It's very close but I think May edges it but no way in hell does he win a poll over Manny on ESB lol
There's a lot of undefeated fighters that no one has ever heard or aren't even in the top 20. Undefeated doesn't mean ****, it's who you fight.
And Baldomir. But there is a few 'belt holder' level fighters on the second tier of Pac's resume as well.
