Pacquiao's KO of Hatton vs a prime heavyweight

how tall is valuev on his knees?

for experimental purposes would like to line up 10 heavyweights on knees and see how many pac could knock out working his way down the line.

david haye definitely getting ko'd

 

he would ko all of em, he would take a massive swing and put all his weight in the punch.

 

Didn't Naz use to KD Johny Nelson in sparring? It depends, a decent HW with a decent chin, I doubt it. Your average "HW from the streets", lol they probably die.

Also in the HW with no weight limit, you see guys who's outweighed by 100lb KO the bigger guy. Check Fedor-Zulu...though Zulu was mostly fat. But Bob Sapp for example is a 250lb meathead who was made to cry on the canvas by a 220lb man.
