If he doesn't give collazo a rematch I doubt that he'll gets pbf. Definitely not at 147. Mayweather ain't coming back down for him. PBF will stay at 147 and say that hatton was run out of the division by collazo and its no need to fight him. As far as Castillo/Corrales i think he would break corrales. Castillo will give him a fight. 50/50
