Ricky Hatton.
Only the one that fought Tzyu.
I think Kostya ruined a bit of his punch resistance.
I agree. Not that he became a **** fighter after the Kostya fight, but I dont quite think he was ever as good after that performance.
and although I picked Hatton by stoppage, I think instead he might win by decision, because when a fighter tries pressuring him with a lot of offense and activity he tends to respond by smothering and mauling them.
