I think Marciano would eventually find Ali over 15 rounds

[IamInuit]

And sometimes not.

Joe would have been the fastest opponent Roy ever faced and from the other side. Roy wins but it would not be easy.

In my humble opinion the Ali/Clay who fought Ernie Terrell and Cleveland Williams would have absolutely destroyed Marciano, it wouldn't have even been competitive. Rocky would have been barely able to lay a glove on Ali because of his defense, and Mariano's short arms.

Marciano might have had better luck fighting the version of Ali after his 3 1/2 year layoff for draft evasion and/or the version of Ali who lost to Joe Frazier in their 1st fight.

I don't think Marciano would have knocked Ali out. I just don't see him hitting him with that kind of consistency.

Marciano was teeing off on fat Don Cockell with flush shots to the chin and had trouble putting him away.

Ali had a great chin and was a great survival artist when he was hurt.

Ali was never knocked out by giants,cant see a small Marciano doing it.

All due respects to the Rock, but the only time he would find Ali would be when he looks up and finds him standing over him during visiting hours at the hospital when Ali visits to check up on the Rock after eye surgery! The Ali of 1966/67 makes mince meat out of the Rock within 6 rounds.

Imho this sums it up^^

Or ali gets told to take a dive by the mob in the 9th rd..marciano must stay unbeaten.

^I think Marciano vs Frazier is a much more interesting fight than Marciano/Ali.

In 1966 Ali fought George Chuvalo and won a unanimous decision. Despite the scores he had a lot of trouble with Chuvalo, who has maintained since that he would have won had the judges scored body punches (he also said the saying you were in a close fight with Ali is like spitting on the Pope; sacrilegious.) At the time many thought that Chuvalo had drawn the blueprint for how to beat Ali.
If a prime Ali had a hard night with George Chuvalo, Marciano would have taken him to hell.

Don't forget what happened to Big George Foreman when he started body punching Ali.

Ali would have beaten Rocky as would have Joe Frazier, Christmas is over.

Aint gonna happen,
Never coulda happened,
Styles make fights,
People make styles,
You can only fight whats out there.

Just be respectful to both legacies, true ambassadors of our sport. Unfortunately born in different eras but it gives us something to talk about with our grandsons/sons/dads/grandads... let it go.

The only thing Chuvalo did with any consistency to Ali was hit him with kidney punches in the clinch (which I heard made Ali piss blood for a week).

I love George and he certainly was a bruiser and caused Ali a lot of pain and discomfort, I don't think he came close to beating Ali, and if people at the time thought he had drawn the blueprint to beat Ali, I think that sentiment was probably based moreso in the public's distaste for Ali at the time than it was in any real logic.

Chuvalo had probably the best chin in HW history too IMO

Ali gave Marciano a good chance though

Brock you are sounding like that prat poster Philosopher with fighting little sections where Ali was hit or hurt. I could do the same with Rocky if I looked hard enough in one fight and had the spare time you have.

The thought was that the way to beat Ali was with pressure, staying on top of him and punching to the body. Ali certainly took a lot of body punches in many fights: He could pull his head away very quickly but not his body. And in close he didn't keep his elbows in tight to protect his ribs (until Zaire), preferring to grab his opponent around the head and pull them down.
Ali was far far from a perfect fighter. Once Marciano got close ( and he would, because he'd make Ali move into him to land his jab) Ali would have problems with his activity and those punches would slow him down.
