He's still a peekaboo fighter though. He puts himself right in danger when he's a foot away from Foreman. A Foreman knockout is the only inevitable result.
I'd pick peak Tyson to beat the old version of Foreman. But the difference is that Tyson would jump in with murderous bulldozing blows and land those crisp hooks and uppercuts when in close range. Foreman would be too slow to avoid the combinations.
Floyd would be too hesitant at times. I just don't see him holding up well against Foreman. The first significant punch Foreman lands would be the beginning of the end.
