Styles Make fights. And I would have wanted to see Mike Tyson vs Rocky Marciano. Marciano had a steel chin and Tyson had unbelievable power. Marciano also had unbelievable power. If Marciano could see off Tyson early, I think Marciano would have scored a late knockout win or points win. Tyson did have a chance at an early KO, however Marciano was rarely troubled in his career. In my opinion. I have Marciano winning that fight by KO.
