mm i say first a tune up fight with JLC (i'd love to see my fellow Sonorense Castillo back in a big fight :) )
then he needs to grow some balls and fight margarito again,he would need to work way harder tho cuase the punches didn't do too much demage to margarito in the first fight
Cotto needs to fight his inner demons, reconcile with his uncle and get a good trainer. Thats Cotto's fight :P and of course make a big come back agaisnt Margarito (for pride).
Arum mentioned a Margarito rematch but Cotto has said that he doesn't want to deal with that guy again. A Mosley match would be entertaining because if Mosley gets passed Berto then it would be a title match for 2 belts.
