Hatton would beat Timmy at either weight. He gave Floyd several tough rounds at 147. Only Floyd had the power to eventually hold him off, and the skill to take him apart. Timmy has neither. And despite his physique, Bradley isn't as physically strong as Floyd is either.
I agree, Bradley is nowhere near as strong as he looks, he definitely has a showy physique. To be honest he looked no stronger than Pacquiao, and physical strength isn't really one of Manny's strong points. I don't think Bradley even has the style to trouble Hatton much actually, Hatton is better in pretty much every way.
I've always defended Bradley and considered him underrated, but I don't think he has either the power or boxing skill/defense etc to really trouble Hatton. Bradley is a good fighter, but I don't see him having much of an advantage over Hatton in any way, or the style to really trouble him. Timmy would come forward and fight, but unlike the likes of Peterdude, he'd be up against someone with faster hands, faster feet, more power, crisper in fighting.
bradley wins via decision. hatton's grappling efforts vs. floyd were overrated. his other fight at 147, he looked like doo doo vs. collazo. i think bradley beats that older version of tszyu.
