I was just thinking of Rocky Marciano versus evander holyfield at like 186 lb for example

I think holyfield would never get tired and that would be a really bad thing for Rocky Marciano because he used to win his fights because he never got tired

Now you have two guys who never get tired and who like to throw a lot of punches

God knows what would happen in that fight but the evander holyfield seems a lot bigger than Marciano

Holyfield is about 6 ft 2 I think but Marciano was only about 5 foot 11

Holyfield has an iron chin and it's hard to picture Marciano hurting him

holyfield took some bombs from Mike Tyson and did not even flinch

That would be one hell of a fight
