I don't think Marciano would have a chance against Lewis. Lewis only lost when he overlooked two bums, against any dangerous opponent he was always razor sharp.

I reckon he would just keep Marciano on the outside all night. Every time Marciano came in he would just clinch al la Wladimir and Rocky wouldn't be able to do anything.


Ironically though Marciano may have a better chance of beating Ali than he would Lewis.

Consider the facts, Ali didn't have the power to get rid of guys that were blown away by big punchers Liston and Foreman.

Frazier gave Ali hell beating him once and another close decision. He only scraped past Ken Noreton after losing their first fight. Foreman literally blew these guys away.

Ali also had a torrid time against Chuvalo again destroyed by Foreman. And he couldn't get Patterson out of there for 13 rounds in their first fight even though Patterson was clearly having serious problems with his back. Liston blew Patterson away twice inside a couple of minutes.

I reckon Marciano's heart, work rate and toughness would have given Ali real trouble, probably a 15 rounder back in the day.

I wouldn't give Marciano a hope against Lewis however, although I reckon Ali would have a real chance at stopping Lewis.
