George by devastating Ko, why? he's an Olympic champion who's a far better boxer. He has better footwork , better jab, better balance, knows how to cut the ring off . Wilder is a very powerful puncher, but honestly he's thin in the midsection, I've seen George get off the canvas and knock a man out. I seriously doubt that Wilder gets off the mat and survives Foreman .
Foreman would win not bc he's again the overatted skilled guy on here concerning skills but pressure would get to Wilder and that's enough for any power puncher ( again see Breazeale fight he STUNNED Wilder with a glancing blow briefly and had him back off ) ,he doesn't throw back if hes being swung on and foreman could take a punch to give one and had a steady jab ,wilder not being able to move and hit at the same time is a real problem here bc he'll need to out maneuver the much aggressive puncher . Its not improbable wilder wins if they fought 3 times but I can see Wilder getting knocked out twice and a third fight wouldn't happen. Either versions of Foreman defeat him but unlike popular belief the 70's one would leave him open to more potential K.O loss from wilder.
