Roy would beat McCallum in both thier primes. McCallum was good but Jones was great. Alot of people say the legends of the 80s like Hearns/Duran/Leonard/Hagler did not fight McCallum but he did not set it up well to fight them. After Curry, he lost his first fight at middleweight to Kalambay and that sort of took the air out of his momentum. And those guys always had each other to fight.
