Rocky Graziano, in his autobiography, "Somebody Up There Likes Me," said he was approached by a mobster (probably Carbo) to throw a fight, but didn't--and lived to tell about it. Jake LaMotta admitted to throwing a fight for the Mob. I read somewhere that Ezzard Charles, considered one of the best heavyweights of his era, totally belonged to Carbo, who allegedly paid him as little as $150 for a championship fight. Sonny Liston allegedly belonged to the Mob.
