Why would Hatton give a rematch to guy a he beat fair and square who stylewise is his worst nightmare? It wasn't a controversial decision, it was close fight that Hatton got the nod in. Theres much bigger and better fights out there for him - Castillo, Cotto, Witter etc... Collazo fought a great fight, was unlucky the verdict didn't go his way, and I'm sure, and the end of the day is immensely grateful to Hatton for putting him on the map
