This was probably Floyd's best weight, he honestly looked like the perfect fighter against Gatti. You'd have to be among the elitest of the elite to challenge him here, and I don't think Tszyu qualifies.
I would be more surprised if Tszyu was competitive than I would be if Floyd won every round. Floyd by wide 10-2ish or so
In what respects? Floyd fought the perfect fight. He showed off the best aspects of both ends of his career, the power and aggression of Pretty Boy and the defense/untouchability of Money.
Floyd UD although Tszyu might have 1 huge round were he hurts Floyd bad a couple of times and nearly stops him but FM hangs on and weathers the storm.
Floyd by very cautious decision, but if he got too brave for his own good he could get caught and hurt very badly, because Tszyu had great timing, underrated speed, and freaky power. That said, I think Floyd would do just enough to get the decision without too many scary moments.
