How long could Marciano last with Klitschko?

[Dropanuke]

I reckon the klitschkos would have beaten the fraziers, marcianos, maybe not larry holmes but defo would have given Ali a run!!
I honestly think Tyson in his prime wouldn't have an easy nite against either klitschko, they are so big and smart, every time Tyson faught a smart man he had trouble

[Dave Hughey]

I agree that such a fight wouldn't happen these days because the two would be in two different divisions.

If it did happen, Rocky's big heart would get him killed.

[brocktonblockbust]

remember Rocky would hit the arms, elbows, hips and really hurt them.

[ElTerribleMorales]

given how both know how to use their height and reach, both would pummel Marciano stopping him by the 6th

[CFH]

He wouldn't land a single punch and he'd be brutally knocked out by the third round.

[Vendettos]

Haye landed a couple on Wlads chin!

If Marciano landed the same hits Haye did to that glass chin of Wlads, it'd have been curtains!



Vitali would be a different story!

[Gandalf]

Marciano was tough, so would get some rounds in and likely go the distance due to Wlad's caution, but far too small. Vitali would knock him out viciously.
