Rocky Marciano 185 pounds vs Cassius clay 190 pounds

[imp]

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 but that's not the topic....Cassius 190 vs Marciano 185...nothing to do with Tyson or anybody else.

Tyson always pops up somewhere.

The Lower the weight the more of an advantage for rocky.
