Depends who fight who. I don't mind that Hatton had problems with Collazo moving up, except that people still think he would beat Mayweather. Mayweather has moved more weights, and has won every fight except one straight out. My problem with Hatton is why didn't he fight Collazo again? If you are in a close fight going up, you should fight that guy again. I give Mosley all the kudos for fighting guys again who beat him the first time. Mayweather gets credit for fighting Castillo again, and for wanting to fight Oscar Dela Hoya again.
