Ricky Hatton has 1 career victory at WW and it was highly disputable and he was out on his feet at the end. Had it gone another round or two he would've most likely been knocked out. He felt so uncomfortable at the weight that he immediately went back to Junior WW. Clottey is way too big and strong for Hatton. He would bust Hatton up with the jab and cruise to a comfortable decision.
Is this fight on the table, or is this strictly hypothetical? For Hatton's sake, I would hope it's hypothetical because he'd have no chance of winning. On the other hand, to the extent it would discredit one of the wins that PBF points to as evidence of his greatness, it'd be nice to see that a fighter the likes of Clottey at 147 could beat him as convincingly as PBF did.
