And by the way Ezzard Charles tried four times to regain the title, Jersey Joe Walcott twice, Floyd Patterson, Sonny Listen once, bla, bla, bla. And how many of these guys had brain damage. (I don't mean emotional, or by a disease.) I'm not trying to be a dick, I'm just enjoying the disagreement.
And one of my all time favorite fighters suffered by having an opponent die after their fight. Which as it turned out was not Mancini's fault. Because the Koreans allowed him to fight knowing about the injury prior to the fight.
