What do you mean Rocco didn't know about Sonny Liston? Sonny Liston went to jail so many times that kept interrupting his career. Then he became a heroin addict and died in a hotel in Las Vegas. How the hell was Rocky Marciano supposed to know if this guy was active or not? when Marciano got back from South America on his cruise with his wife it was April 1956 and he was only four months away from his 33rd birthday.

Sonny Liston was born either 1930 or 1932.

Marciano was born in 1923.

Sonny Liston was six foot one and he weighed about 220 pounds

Marciano was five foot ten and he weighed about 184 pounds

Are you calling that a fair fight?
