Suppose referee Jay Nady gave Tzu a second knockdown instead of stopping the fight. It is very likely that Tzu would have had at least a 10-7 round. Of course he might have put Zab away for good after the second knockdown. Could Zab have survived and gone the distance or even won or draw? How do you think the fight would have gone?
Judah never had the punch resistance or mentality to beat a legitimate great like Tszyu. He was a pretty cringeworthy Mike Tyson wannabe, photos and footage of the two of them together show one man in absolute awe of another. Judah's lack of gratitude to Nady for ensuring he wasn't carried out of the ring was really embarrassing man-child stuff.
Judah definitely made a mistake jumping back to his without taking the full eight count. He might have been able to continue but I will always believe Tzyu would have had his number because of Tzyu's impeccable timing and the fact that Judah was a south paw that was susceptible to Right hands which was Tzyu's bread and butter punch. The way to beating a beast like Tzyu was to back him up like Hatton did which took away his power and timing. Staying on the outside against Koysta was always a mistake.
