Do people actually think Marciano would beat Ali?

[Dark Lord Al]

In reality Clay would have beaten Rocky as you can only be as good as your era.
But i feel the same about Clay v a fighter like Lennox Lewis / Klitchko's i just dont see him winning against the modern day monster champion.

So the Ali that beat Terrell or Foreman could not beat Lewis or Klt brothers?

No , well not the best out of 3.

Its just stupid to say Clay could beat the likes of Lewis or Klits , and on the other hand say Rocky had no chance against Clay.
