This content is protected Apparently this was around the time that Marciano challenged Liston to a sparring match for the derogatory things he was saying. Marciano certainly ballooned up in retirement, though he was already gaining weight during his championship reign (which i plan to do a thread on). He was around 230ish here What do you guys think would've happened? Let's say they spar for 2-3 rounds, does Liston knock him out cold, perhaps butchers him for the rounds? Or does Marciano make Liston respect him?
