Someone already said it on another thread...
It's a win-win for Manny.

Lose to Hatton, and you've lost to a champ at a higher weight class. The naturally bigger man.

Beat Hatton, and you cement your legacy as an ATG and true p4p champ.

On the other hand, if Hatton beats Manny, I don't care how much Ricky's fans may want to vault him to the top of the p4p rankings. He won't get there by beating a great 130-pounder.
