Although Hagler was a great middleweight, I think Spinks would have beat him on size. I think Hearns would have given Spinks a better fight than Hagler. Stylewise Hearns could move up and fight better guys more evenly. Why? I am not sure. Hagler beats Hearns, but Hearns could beat alot of guys who Hagler would stuggle with. The Spinks Jinx would have hit Hagler in the first or second round and I doubt Hagler would have pressed forward much.
