The most devastating punch of all time?

Tyson hits Trevor Berbick and Berbick goes down so hard he bounces up and goes down again, to which he staggers up and goes doen again.

I would disagree. That punch looks unexceptional, even as Berbick's unable to deal with its aftermath. I'd nominate the shot Marciano beat Jersey Joe Walcott with, a short 5 inch devastating right cross to the jaw that reconfigured Joe's face sideways, winning Marciano the bout on a one punch KO that he'd been badly trailing in.

Marquez's right hand that starched Manny on Saturday was more devastating, for that matter. Many of Tyson's KOs were more devastating, in that the victims of them went down and stayed down, unable to even try to stagger themselves up.

Good candidate. Punch, guy falls down on his face, doesn't get up.

Here are 10 good ones. The Rocky KO starts about 3:15 into it. Walcott crumbled in slow motion, held up first by the middle rope, then by the lower rope, which prevented the classic face first fall.
