ok u lot, start arguing about who wins this. i'll call a draw but who do u think wins at what weight, if you think the weight makes the result different?
Well, the Hearns who shattered Durán would stop Canelo imo. Hearns at MW wasn't a hard enough puncher to stop Canelo just get his respect and outbox him. A Barkley fight situation could also happen.
Hearns punch resistance was a problem for him. Canelo is a much bigger puncher than SRL was and SRL stopped prime Tommy. If Hearns fought Canelo, he might win a bunch of rounds but eventually Canelo would catch him with a big body shot that would slow him down and he'd end up on the ropes covering up too tired to move like he was when he was stopped vs SRL. I doubt Canelo would be able to knock Hearns out cold like Amir Khan or something but he'd eventually land a big shot on him and Hearns would either slow down grimacing in pain or he'd have to take a knee or something. On the other side of things, I don't see how Hearns would stop Canelo. Canelo has a granite chin, he's never been knocked down in his entire career. GGG is a much bigger puncher than Hearns ever was and Canelo ate GGG's best shots like skittles.
Hearns was a weight bully for most of his career, when fighting below 160 pounds against guys who were naturally much smaller. The moment he stepped up in weight to fight guys naturally as big as himself in Barkley and Hagler, he immediately got exposed as the over-hyped weight bully that he's been in his career. His style mainly worked on naturally smaller and shorter guys, where he could make use of his height, reach and power advantages. Once they were taken away from him in the higher weight divisions against guys his own size, he proved to be relatively too low skilled and lacked adaptability to fight effectively. His power did not have the same effect on guys his own natural size, so he really wasn't that powerful. His power only ever looked devastating against naturally smaller guys, which isn't that impressive. Hearns is a nobody in front of Canelo. He walks through Hearns and KO's him Amir Khan style inside 6 rounds. Hearns poses literally no threat to Canelo Alvarez whatsoever. His power would be as useless on Canelo as it was against Barkley and so would his straight punches. A total mismatch this is!
Barkley threw out of the blue haymakers in a very unorthodox way. He hit Toney with a punch Toney said was the hardest he was ever hit.
