Honestly foreman and going 2 for 3 with Frazier is already a pretty small list. Am I in the minority if I favour Foreman against Louis?
I don't subscribe to the notion that Lennox had a glass jaw, but the truth is he was knockoutable even at his peak. I imagine he could get stopped here once or maybe twice. That and I think Joe Frazier's style was all wrong for Larry Holmes.
As silly as your post sounds, I really like it. I think you hit this one perfect. Young Foreman could over power older Liston, we already know he always beats Frazier and he could possibly beat the younger version of himself.
Whats the chances that someone informs us of every date for every fight.? There really is no need, we are all fully aware of the timeline.
Joe Louis from Jack Sharkey to JJW 1 could do it. I think his likeliest loss would be to Liston whereas Frazier and Foreman seem to me built for Louis (relatively / as built for as a top 10 HW could be for another)
IMHO, Joe Louis and Evander Holyfield would have had live chances to do that. They would both have to show up ready to employ the proper styles each time. Louis would need to box Foreman and Liston, and slug with Frazier. Holyfield would need to box Liston and Foreman and get into the trenches with Frazier. And Frazier would be the biggest problem of the three for Evander.
How about Foreman? Considering the stylistic advantages against Joe it basically comes down to him VS Liston, assuming we give him a loss against his younger self.
