Marvelous Marvin Hagler is a sporting legend. Often called the greatest middleweight boxer of all time, he held the world title for 12 defenses, including bouts with Sugar Ray Leonard, Thomas Hearns, and Roberto Duran, which entered fistic folklore. From his wild early fights in the boxing wilderness of Brockton, Massachusetts, Brian and Damian Hughes trace the blazing trail of Hagler's career: the controversial defeats subsequently avenged, a riot-scarred title win in London, and his unification of the middleweight crown. Hagler became a huge favorite, taking on all comers while never taking a step back. And so to "The Ring "magazine's "greatest round of all time" against Hearns, his ferocious battle with Duran, and the still-controversial loss to his nemesis Leonard. "Marvelous "tells the story of Hagler's extraordinary life for the first time, separating truth from myth to get right to the heart of a complex and charismatic man.
