The comparisons between Hatton/PBF and Gatti/PBF

He had seven weeks to carry on cutting down on his usual fat, which is never an issue, but he had no time to put 7lbs of muscle on. Without steroids most people would struggle to put a lb of solid muscle on in a week. Hatton had to do that whilst cutting a load of weight.

At least Collazo was fighting at his natural weight. Hatton wasn't. If both men were fighitng at 147lbs, then yes, Hatton would have an advantage but he was used to fighting at 140lbs and didn't have enough time to add muscle.

Hatton was noticably less ripped than he was at 140lbs and had a lot of stamina issues, despite throwing less punches. Had he had time to gain that 7lbs properly, neither would have been an issue.
