How is Tyson not the greatest heavyweight puncher?

[ross]

Sure, he blew out lots of people early on with one punch, but by and large they were early career cannon fodder. Later on, if you notice, he didn't get that many one punch kayos.

Ok well from when he fought the world champ on, I can think of...

Berbick, Tubbs, Spinks, Carl Williams, Tillman, Frans Botha, Etienne as one punch KO's. Those are world class guys (at the time anyway) going down from one punch.

yeah, you could argue that. The point I was trying to make is that Berbick and Williams (at least) were actually stopped on their feet. They had got up but were in no fit state to continue. Spinks had already been knocked down, and Tyson then finished him off. I think Tyson was a fearsome puncher, but in his prime he didn't overly rely on that like he did later, he threw combinations and it was his skill at finishing off people that was his greatest strength rather than his pure punching power.

The ref stopped Berbick from falling back down!
