I am in the minority but this would be a good fight. I like Hagler but Canelo is skilled and would definitely win some rounds. Hagler had great stamina and would ultimately wear Canelo out and bust him up. Hagler didn’t have one punch KO power compared to big punchers but he hit hard enough to do major damage. He could box you or go to war. Canelo has a great chin but I don’t see him finishing this one on his feet. Canelo wins close decisions and Hagler lost his most famous and last fight on the cards to SRL. This is the one area where Canelo has an advantage. Moot point because Hagler wouldn’t let him hear the final bell. The fight would probably go ten rounds because Canelo would try to box him. Hagler was never knocked down and never lost a war. Prime Hagler was a bad dude.
Marvelous Marvin Hagler takes this one by close but unanimous decision over Canelo Alvarez. Alvarez has a tough chin as Hagler does. But Marvin disrupts Canelo's rhythm, with his stiff right jab, combinations, and movement. Alvarez though consistent, could not hurt Hagler, as he took bombs by Hearns and Mugabi. Alvarez will land at times to the body. An attempt of a late rally by Canelo falls short. Good Fight.
In Vegas canelo by robbery. In every other city hagler by close but clear decision. Same like ggg. Hagler vs ggg would be a fu... epic! And probably one of the best fights ever
