Rocky Marciano 185 pounds vs Cassius clay 190 pounds

[Vendettos]

Marciano beats every heavyweight in history in any era because hes undefeated and he never fought guys past their prime...yeah right.

Rocky could never hang with ali or tyson in their primes.

Rocky was a great heavyweight/crusierweight but not in my top 5 and many others.

Agreed.

The thing you need to factor in is the extreme technical influence in boxing training now.

Fighters are stronger now I believe than they were back then, boxer can train muscles that Marciano never knew he had.

There's a huge list of people I have beating Rocky now.

K2
Foreman ( old and young )
Lewis
Briggs
Bruno
Tyson
Holyfield
Haye
Valuev
Ali

Size is the main issue against him.

Was he ever hit by a Klitschko straight right for 12 rounds? Could he take a fight full of Tyson right body hooks? Would he have even got close enough to Valuev to hit him once?

Hardly.

That said, some of them would have probably beaten Ali also.
