What a silly question to ask on a forum dominated by blacks,who do you think they are going to pick ? You might aswell go onto a white supremacist and ask the same question.
Marciano is naturally smaller than Tyson so I think that Tyson will stop him inside 6 rounds. However, if Tyson can't take Marciano out early then he'll have a serious problem in the late rounds.
I gotta go with rocky based on Ali saying his arms hurt "sparring" for the computer fight, the fact that rocky broke some other fighters arms and that every man who faced him said he was deceptively hard to hit. Oh and rocky is the epitome of a pressure fighter the likes of whose NEVER scared or intimidated. Mikey never faced anyone like the rock. That. Being said prime mikey is a nightmare for anyone.
The problem with the internet is the same thing that makes it great...everyone can voice their opinion. Unfortunately even idiots can voice their opinion. God I hate racist idiots!!!
Trust me, most caucasians would pick peak Tyson to win this matchup as well. Marciano has the conditioning advantage by far but Iron Mike is equal or superior in every other way.
Marciano had a far better chin than tyson thats for sure but it was possible to put him down and with Tysons accuracy, speed, power and head movement Tyson takes it within 3 or 4 rounds. I dont see how Marciano could win unless he gets a lucky punch
