The win will mean nothing due to the weight. If Floyd had dropped down to lightweight he might have got some credit.
Hatton and Corrales were both high profile fighters with undefeated records at the time Mayweather faced them. And of course De La Hoya.
I have to say Delahoya is his best opponent...Delahoya was the much bigger man and made floyd travel to 154 to fight him
I agree with the De la Hoya shout. I do believe it will be his toughest fight though. Due to circumstances such as possible ring rust etc.
I'd have to say Hatton, Then De La Hoya. But like Pea said, P4P wise JMM is up there with both. (I love "Chico" but dude's mind wasn't right for the PBF fight)
