To repeat what others have said--if Judah can catch Ricky early on, he could win by KO or cuts stoppage. He'd win at least 4 out of the first 6 rounds no matter what. If he couldn't end it--or significantly slow down Hatton--in those rounds, he'd likely give up and give up a lot of later rounds, and possibly get KO'd. So either guy could win by some kind of stoppage--Zab early or Hatton late. But if it went to the cards, I think it's a very close fight (Zab, as the more skilled boxer, dominates early and fades late).
