Hardest puncher in the history of Boxing? Shavers/Wlad/Lewis/Foreman/Tyson?

Foreman had genuine world level KOs, both in his first career and in his return. Shavers comes in second based on the testimony of all those that faced him. Tyson could be second too, or at the very least, 3rd. Not sure how or why Wlad is getting a mention.

I'd say Foreman but when Ali says Shavers is the hardest you kinda gotta side with him.

Shavers or Foreman

I'll have to say Foreman. Tyson was a devastating puncher but Foreman was effortless. Yeah, why is Wlad on here? This. Foreman was effortless, no leverage....his jab alone was powerful to stun opponents. Heavy heavy hands.

Yeah Shavers or Foreman

why is Wlad on the list? Emanuel Steward and Freddie Roach said Wlad had hardest single punch whom they ever trained...

between shavers and foreman

I'll have to say Foreman. Tyson was a devastating puncher but Foreman was effortless. Yeah, why is Wlad on here?

why is Wlad on the list?

Non Heavyweights, Julian Jackson. And no one else is all that close IMO.

From the limited footage I have seen, I'm going with Shavers on this one. Tyson had more effective power due to his speed though.
