If zab was given the time in between rounds to recover. He would have simply shut down. Let's say him leaning back with his hands down was all done for the purpose of showboating and he took his count got up, the bell rang and he had the rest in between rounds.

At the beginning of the next round, Tszyu would have picked up where he left off and continued to methodically stalk judah and wait for the next mistake while just hammering away. So if we were to give zab the benefit of the doubt and saying that he tightened his defense and didnt make that same mistake again.... would he have won the fight?

Sorry, he would have been battered like an onion ring for the next couple of rounds and taken the beating of his life. Its a fact that after getting rocked by someone, Zab shuts down and tries to finish the fight on his feet without assuming much if any risk after that. I might even go as far as to say his star would have burned out that night and he probably never wouldn't have made it as far as he had in his career. After fighters take beatings like that, they are never the same. That punch that put him on queer street and the stoppage is probably the best thing that happened to him when you consider him taking a gruesome beating, being stripped of his confidence and some of his mental competency or worse..as the alternative.
