I know that it was a different era but watching Marciano v Walcott I. Walcott was clearly the stronger man and Marciano broke every rule to win while Walcott kept it clean.
They both took liberties and fought dirty throughout the fight, which isn't uncommon in a title fight.
Marciano didn't fight clean, it's a pity but that's how it was. How much was calculated and how much was sheer wildness is up for debate I guess.
I don't know if Rocky was the dirtiest champion of all time but he might be. He's definitely in the running.
Maybe at heavyweight, but across all weight divisions? He's not even in the top 5. There are so many fighters such as Greb, Tyson and Zivic we have to consider Zivic is the cheating GOAT tho
Tyson and Dempsey are up there as well. Zivic dirty fighting was more advanced. He could make a guy butt himself or give the laces. Marciano on other hand just hit on the break, low and after the bell repeatedly. He wasn't as smooth with it.
