Really do not know how people can say Roy would have beaten Hagler at middlewight. Roy was a progress in work and Hagler was the finished article at the weight. Would Roy at middlewight beaten Mugabi ? maybe but do not believe he would have beaten Hearns and certainly not Hagler. He would have made it a brutal slugfest as that was his best chance and I do not think Roy would win as he would become negative and disillusioned with his bombs bouncing off Haglers head. I even think that Roy would not have fought him and would have moved up to super middleweight had they been in the same era.
