Heavyweight Roy Jones vs Prime Marciano

[xAUGUSTUSx]

Marciano would wear him out and KO him.

[Megamasterking]

This is not serious, Marciano would brake RJJ's jaw. The thruth is that RJJ wouldn't want to fight Marciano. Marciano's power was huge, no steroids, natural. So, if you consider Marciano's will to win, heart and granite chin, RJJ is in trouble.
