Which boxer did the most damage to Mayweather? His physically toughest fight?

[Syf]

Technically? Hernandez. Dude broke his hand on Hernandez head and took a knee.

Then Castillo.

Then Maidana.

[Sugar Adam Ali]

Then Castillo.

Then Maidana.

Good call,,, I forgot about the famoso fight... I would also throw the chavez fight in there,, floyd had to fight his arse off vs the possessed chavez

[Don Pichardo]

PAC.

PAC made floyd dehydrated before even the fight started and had to inject 750ml of IV fluid

Maybe. But he didn't do much during the fight. When it counts.

Another attempt at a Maidana lovefest OP?

Looool. Truth.

Voted for Castillo but after him Cotto was the next.

[DeandreXI]

Cotto touched him up pretty good. Maidana did too, Chino was pummeling Mayweather endlessly. Castillo obviously.

I was thinking about including Jesus Chavez and Carlos Hernandez in the list, along with Ricky Hatton and Zab Judah. However, there are only 10 slots when making a poll. Good answer, Syf.

I voted for Miguel Cotto.

[BoxingIsGreat]

None. He was too good for his generation.

[Panopticon]

Cotto. He dished out so much punishment Floyd seriously considered retirement after that fight. Maidana put some punches on him too but I dont think he is as strong as Cotto.
