I would love to see this fight happen. Judah has a style that troubles Hatton greatly (very fast southpaw counterpuncher) and Hatton has a style that troubles Judah (rough swarmer who never stops pressuring). A focused Judah should be able to stop Hatton without much difficulty, but at this point I'm not extremely confident in him. I would still pick Zab to win though, mid-late TKO.
Right now, I'd pick Hatton. When Zab was at his top form at 140, I might pick him, but you can never tell with Zab...
Zab takes the first five rounds utilizing movement, hand speed and superior firepower. then inexpicably fades, gets hit by a haymaker, and be on survival mode for the remainder of the fight. Hatton UD.
Zab wins the first two or three rounds, but Hatton takes the shots and keeps the pressure on, either stopping Judah in the late rounds or getting a UD. Someone who mentally folds over virtually ANYTHING is a dream come true to a pressure fighter. And if Hatton could get Mayweather against the ropes and land punches, you better believe that Judah will be taking them too.
i think Hatton's style and pressure would frustrate Zab and break him...plus he is not a great in fighter and fades late in fights.
