I think it is too early to tell. These type of questions are best left til after the fighter retires and their career can be digested without the hype. Eras also plays a big role in the equation.
I have to side on NO,, at least for Hagler Id say no.. Only because Hagler's Jab really busted guys up and he was really tuff and hard to hit clean.
Ggg would annihilate both, hagler far worse because his chin,toughness and size but the beating he would take would effectively end whatever prime years he had left. He'd corner srl and dispose of him is sad fashion. Thing is, srl would be hated in this day n age of social media, my god he'd be only a few dozen levels below fmj is the hate dept
Hard to hit clean, and putting his jab against ggg jab is a terrible night for him, never mind the difference in talent and power is immense
You can give both Hagler and SRL a bunch of designer steroids and they still wont beat Golovkin, the man is a boxing machine. Who else can outbox you, and knock you out in the process? The triple God thats who! :yep Also they would be considered bums if Golovkin beats them atsch
Hell no !! Hagler is a highly skilled Middle fighter on his resume alone would decimate anyone on GGG resume ! Haggler power and precision punching would cut the easy to hit GGG to pieces!
With his incredible record, amateur and pro, we are getting to the stage where we have to accept gennady golovkin is an a.t.g. It's not far fetched to see him beating anybody. To dismiss his chances just diminishes your credibility Imo.
