That fight was the 1st time I saw Hatton fight and I was impressed by the heart he showed in the 12th round. It was a while ago, but I recall thinking that the 12th round could have been easily scored 10-8 for Collazo - that was as much a KD as the one Hatton scored in the 1st round. Even without a KD I could see it being called a 10-8 round - Collazo was fucking him up badly and Hatton didn't do a thing but survive.
I had Collazo winning by 2 - 3 rounds I think; I gave him the nod in many of the closely contested middle rounds of the fight due to his more accurate, clean, and more damaging punching. Collazo also clearly won the 10th and 12th rounds. I was cheering for Hatton, but he lost that fight. It was not an out and out robbery however.
