Idk, Tyson and Foreman both in their prime would be a hell of a match but Tyson would take most of his punches to the top of the head being shorter and Tyson had a way of blasting from the bottom up and if he caught Foreman with a good snap to the kisser I think it's goodnight for the big man. Also, he ate punches for breakfast. Id be stupid to count George out though if he could keep Tyson at a distance and use he's reach as he was so good at lay it on the body and avoid the ropes he'd surely give Tyson something to remember him by. If only we could have seen it.
