Zab Judah won 3 out of the first 4 rounds against Floyd Mayweather, then as soon as Floyd Mayweather adjusted he couldn't deal with it. It was nothing to do with Zab Judah falling apart, it was down to Floyd Mayweather changing his tactics.

I've never seen anyone get as much credit as Zab Judah, for winning 3 rounds out of 12. He was tripled in power punches if i remember rightly. And he took a beating in the later rounds, i have no idea why you would of wanted to have seen a rematch.

As for your other question at 140 he has a chance, at 147 he has no chance.
