Lewis has more power than Foreman? More heart than Foreman? Better finishing ability? More killer instinct? A better jab? Better footwork? He has none of those things.
Many opinions, which happen to be incorrect. You are also mashing together old and young versions of Foreman. Young Foreman did not have an impressive jab, and certainly nothing comparable to Lewis. Lewis certainly has more one punch power than Foreman, not only because he is 30lb bigger, but also because he is technically better in how he throws his punches. When Lewis touched guys with his best punches they dropped like they got shot. I'm not talking about 210lb Frazier either, but 250lb peer size fighters.
I might call them equal on heart. I used to doubt Lewis' heart but the Vitali fight proved that he could put his hand in the fire when he had to.
Foreman is not getting 1 punch ko'd and Lewis gets destroyed if he tries to brawl like Lyle, he likely gets caught by Foreman's slick timing and at some point Foreman is able to finish it, Lewis always had to set up his big shots which Foreman would make very difficult with his bicep control and shoving, he would bring Lewis into a brawl he knows Lewis can't win
People in the classic part of the forum are generally and globally fond of nostalgia. I don't mean every last individual. https://www.boxingforum24.com/threads/h2h-heavyweights-mount-rushmore.717538/ Here Foreman is clearly behind Lewis and Louis and Ali. I would rank the four of them like this: Lewis, Ali, Foreman, Louis...
Followed by opposing opinions, such as, “Foreman didn’t have a good jab in the 70’s.” Someone forgot to tell his opposition. Lewis’ jab was, “incomparably better?” Please. “Lewis certainly had more one punch power than Foreman…” The mother lode of incorrect opinions.
There are entire videos run on Lewis' jab and how versatile and controlling it was. Here's one of them. This content is protected
Lewis had better jab and footwork than Foreman, I think heart and power are similar, Foreman had better finishing ability and killer instincts.
