Did any other boxers in history have knockout power like Julian Jackson?

You're missing the point. Barely any of his knockouts are on film. Pretty hard to judge what he does and doesn't do when we have less than 1/10 of them on film. It would be great to have another couple of dozen available even if most were against lower level guys.

Jackson is a more skillful higher level fighter too. Earnie was good but he was also limited. He just had that big power, more so when he was fresh.

Welcome to the forum too.

 

Galaxy was absolute GRANITE

 

I think like a lot of things in Boxing, there are far more many lethal punchers than first considered.

 

Benn hit very hard at middle ! Like Jackson it got him out of trouble sometimes. Both of them were kill or be killed types .Benn became more of a boxer at super middle.Without that power they would of been very average

 

Bob Foster is the very first to come to mind.

 

Foster or maybe Arguello in terms of older guys Fitz although footage isn't great but a lot of big knockouts especially when he fought guys his own size. Joe Walcott another freak power guy but no footage unfortunately.

 

Bob Fitzsimmons has to be mentioned here. His KO record is more impressive than JJ in my opinion and his power was unreal.

 

Plus he was a super middleweight knocking out heavyweights.
