Would Foreman and Liston really blast out Tyson in two rounds

If Foreman fights Tyson like he did with Frazier, I could see him knocking Mike out. Liston? Not so sure. He didn't weigh that much (210 or so? might be wrong). And yeah he had a jab, but he wasn't Buster Douglas. This would be a much more even fight I think, though I'd favor Tyson personally.

Foreman is one the few guys I'd probably pick over Tyson.

 

Quite true. But I still see Foreman destroying Frazier inside of 6 rounds, simply because Foreman would not be backing up like Ali, making himself a target for that left hook. He would stand his ground and swing away with both hands at that stuck-out chin en route to victory. Unfortunately for Frazier, he had one quite predictable cannon to Foreman's two more versatile bomb launchers.

A wild card could be Frazier's determination. What if Foreman somehow offended Frazier as deeply as Ali thoughtlessly did? Frazier at his peak was a much faster bobber and more effective body puncher coming in than in Jamaica. His right was better and could actually reach a tall opponent's head with power (see FOTC Round 15 after knockdown). That night Frazier had a shot against any man ever. He beat a star-studded crowd's favorite at the favorite's own coronation! I would be rooting for him myself against Foreman.

 

I would pick Foreman to win but not in the first 2 rnds. But he'd have to win by the 4th or he'd be out of gas.
