Well depending on how the Pac fight unfolds, we could definitely see Floyd double dip and rematch Pac if the fight is close or somehow controversial like the Maidana one.

Floyd will FOR SURE go for Cotto's middleweight belt. Cotto is a very winnable opponent (I guess that's fair to say since Floyd has already won vs him) and he gets to say he was the LINEAR middleweight champ, not just the holder of some meaningless trinket.

After that, I could see him going after Danny Garcia or Amir Khan. Maybe even a Canelo rematch.
