Zab is a serial killer? Yeah when he is in their with someone who doesn't belong in the ring. Zab has never KO'd a top fighter early. He had nice success against Tszyu, but he was never on the verge of knocking him out and no one was worried to Kostya Tszyu's survival. He was on his way to possibly getting outpointed or stopped later, but that stopped as round 1 did.

He was doing nice against Mayweather, but by no means was on the mend of stopping him. It was more of Mayweather laying back then Judah winning.

Baldomir was never in danger of getting stopped. Even when Judah was winning every round, everyone knew that was going 12.

Pineda was in trouble in the 2nd I think it was, but bounced back to get a very questionable decision. But again, Zab was winning rounds, it was an issue of winning rounds not surviving them for his opponents.
