I only confidently think he beats Golovkin. I think Hopkins is an all time great middleweight but Ray, Marvin and Carlos are the elite of the elite
Hopkins was a pretty big middleweight. I think he beats GGG for sure. I honestly think he beats Hagler as well. I think Hagler wasn't the biggest middleweight. I got Robinson over Hopkins. Hopkins has always struggled with athleticism. Hopkins vs Monzon is a pick'em fight for me but gun to my head would be Hopkins.
You'd have to be delusional to think he beats Golovkin. His spoiler style wouldn't work and he doesn't have the speed or power to keep Golovkin away. It would look like the Kovalev fight where Hopkins tried to be cute and got dropped. But Golovkin isn't like Kovalev, who went a bit easy on him. Golovkin is a ruthless character and would gladly beat him up very badly. Shame we didn't get to see it.
Beats Hagler, Golovkin. Loses to Robinson as Hopkins did seem to have issues at times vs speedy athletic type fighters. Also loses to Monzon.
