Yes BUT Charles fought a prime coming into his own archie moore, while patterson fought a much older past his prime archie moore. If you watch the film, patterson vs moore was one of archies very worst fights on film. He seemed to have lost his movement and fluidness, strictly relying on turtle shell defense by that point.
1. Charles lacks a heavyweight punch compared to whom? He might punch harder and certainly more effectively than the four fighters you are mentioning. Your "thinking" that someone hits harder than someone else is not evidence. 2. Personally, I don't see what Ali, Liston, or Maxim have to do with anything. Patterson did not stop any of them, nor come close to doing it. I don't think the Maxim fight was a robbery but that is a different issue and anyway Patterson was green. It is difficult imagining Charles doing much worse against Liston, or even Ali, than Patterson did. Charles did defeat a good big heavyweigt, Louis, while Patterson did not. He stopped a big and very durable heavy, Baksi, while Patterson did not. 3. I don't really know who punched harder between Charles and Patterson, but I don't see a great deal of difference between them as punchers. Charles knocked out more rated heavyweights than Patterson--and he knocked out a ton more rated lightheavyweights, which I think is relevant, by the way, back in an era when fighters moved back and forth between these weight classes all the time.
