Which other former heavyweight champs could have stopped Berbick in 2 while he was champ?

A young Bruno would have a chance.Berbick was not hard to hit and was a total header ! Yampy enough to stand and fight frank before he got worn out .anyone frank could hit early he could KO .Who knows what berbick would do on fight night .I doubt ho knew himself.Would be fun.

 

That's a long list
Marciano
Foreman
Liston
Lewis just to name a few

 

Dempsey??? Trevor Berbick was a 6'2" 220 lb physically fit black HW who beat John Tate, Greg Page, Pinklon Thomas, and went the distance with a prime Larry Holmes. Dempsey wouldnt have gone anywhere near Berbick much less knocked him out. Give him a 168 pound pasty white frenchman who had been knocked out by the best middleweights he had faced a decade earlier and maybe you have a case... Oh wait, he went four rounds with Dempsey... nevermind.

 

Berbick has a much better resume than one hit wonder 300 pound Ruiz.....Ruiz has the Bodybuilder thats it and mailed it in in the rematch while berbick came to fight against tyson and showed no fear.

 

Probably not. Though
most ATG heavyweights would stop Berbick. Styles make fights. And it's what Tyson did extremely well ( fast hands and feet, coupled with great power and angles) Tyson was almost perfectly built to destroy Berbick that way. Like Foreman was perfectly built to destroy Frazier ( Probably Tyson also) aggression, fast hand and feet with power was perfectly suited to destroy Berbick.... Not many heavyweights could duplicate that.
