Size is irelevant with Marciano, he would eat every single heavyweight if they were born in the 1930s. I think people underestimate the role of genetics in that era, guys like Fury wouldnt have enough to eat, and no competent steroids would be available. Beterbiev would be ate for lunch, we arent talking boxing, we are talking about pain endurance. The worst heavyweight in 1950s era has more masculinty and testosterone than steroid pumped Anthony Joshua, let a lone Beterbiev and the rest.
Different era, different times, that Walcot had more testostorone from genetic perspective than steroid pumped Anthony Joshua, war experience and iron will. Todays heavyweights or anyone for a matter a fact are gen-z millenial steroid users, they have all the equipment, all the money, all the steroids, all food and their main job is to box. 99% of past boxers are military men, firemen, regular workers. I think Marciano in his prime would break both Vlad and Furys spine over 15 rounds, and if Fury and Vlad or AJ would have been born in the 20-30s, they would probably be cruiserweight as well, where would they have a luxury they have today, a daily food to keep their muscle, a sterodis, protein, gyms with air conditioning. No heavyweight today could match older ones in their era, and we can only dream what could Marciano if he had acces to today luxury equpment, steroids and quality food, he would eat Mike Tyson. Millenials are wimp generation compared to the Silent generation.
If Callum Johnson can hurt Beterbiev, Marciano surely can, and it's hard to definitively pick a more ruthless finisher at the 190lb range than Marciano. If AB gets hurt, especially early, I give it to The Rock all day long. Would be a cracking fight while it lasted though. Theres also the resumes to factor in. AB's best win is probably Gvozdyk, who was an excellent fighter but, he ain't no Archie Moore, Ezzard Charles or Don Cockell, two of which are arguably the greatest LHW's of all time and Don Cockell was no mug.
That level of intensity and work rate in the 14th and 15th rnds after literally beating the crap out of each other for the previous 13 is verging on super human. These guys weren't athletes like many of today's boxers, rather they were hard as nails from the cradle to the grave fighters. Anyone who thinks AB just rolls over Marciano is a damned fool!
You are telling me Tik-Tok generation is superior than SilenGen one? WHat is next, Social Justice Warriors are more brave than Vikings?
And in many fights look like he had been in a car accident. Imagine what someone like Beterbiev would do to him. He'd have more than a bent nose.
Marciano had to practically beat Archie Moore and Walcott to the brink of death before the scores were settled in their give and take affairs. What kind of experience has Beterbiev faced to ready him for when he enters the eye of the storm that awaits him in Marciano? Gvodzyk "The Nail"? More like the "lawn chair" the way way he folded and said no mas. Gvodzyk "The Lawn Chair" would also be known as the door matt if he had to face , Walcott, Charles, Moore, Marciano multiple times in a short time span.
