I think it's clear that if Floyd beats Hatton, the winner of Cotto/Mosley is the person he needs to fight next.
The winner of Cotto-Mosley will bring the biggest potential payday, will have the best credentials, will be the fighter that HBO and the fans will want Floyd to fight, etc.

Floyd will have to fight the winner of Cotto-Mosley, or it will look clear that he's ducking them.

Floyd-Cotto at MSG in Summer '08 would be pretty damn cool to see.
