Muhammad ali said he had trouble with rocky in their simulated fight. And rocky was 50 something I believe. If that tells you anything.

It tells me Marciano is underrated by most fight fans today. i mean look at Ezzard Charles. After fighting Marciano he goes from being a winning fighter to a losing fighter.
That first fight with Marciano that went the distance. Charles got beat up real bad. AND EZZARD CHARLES IS AN ALL TIME GREAT. Ezzard Charles was a much more talented boxer then Marciano. For those who say its cause Ezzard was to old. Marciano was to old to. Marciano started he was 25 started old. Thats old for a heavy. Ezzard still went from being a winning fighter before he ever fought Marciano.
To being a losing fighter
Anytime a guy with no where near the skill of Ezzard Charles can do that to a guy with Charles skill.
Marciano can fight. 8 months in training camp. Marciano Go hard every minute every round

Would Rocko have bulked to over 200lbs or cut to 175 or under if he fought today?

[Rusty Tromboni]

Horribly against Fury. That's all that matters.

Honestly, I think Marciano at Cw would be a P4P sensation. Not on the level of Lomachenko, but still one of the very best we've seen since Duran. I'd say I'd favor him (narrowly) over Usyk - who is hismelf a very special fighter. Marciano was a savge. Like a Olivares who didnt't bitsch out when his opponent hit back. Or like a Frazier who didn't just do two things: the same predicatable attack, and flop on the mat when he took a punch of the chin. Marciano was a beast.

Louis would probably starch most guys. Then Fury would do all sorts of dirty things to him. Even Harvey Weinstein would get offended.

Marciano aint making 175. He spent 8 months in the training camp just to make 184-187. There is a reason why Marcianos a heavyweight and Archie Moore even at same weight as Marciano is still a Light Heavyweight.
It has to do with strength for one. See Marciano could never get to 175. like Moore could unless he lost to much muscle mass cause hes not a light heavyweight
Marciano weighed 192 his first professional fight

Why was he cutting weight fighting at heavyweight?

What do you think he'd weight today then?

He wasn't cutting weight .He was minimizing body fat. Weighing 200s not an advantage for him. Foreman weighed 260 -275 when he made his comeback. It didnt give him more power. How come Fury at close to 300 cant punch through a wall?
But to compete as a heavy today he might need to weigh 200 By law i mean

The brain of Rocky is going to fare quite well, let me tell you.

Ramirez weighs 195 in the ring and dehydrates to 175 no problem. He's also 6'3" and low bodyfat.
