The size difference is vast in reality, go like for like and there's a good chance Golovkin would be a division or two higher than Hagler.
I say that Canelo is actually naturally heavier than hagler. When he competes at 160 He walks between fights around 175 pounds being very fast and explosive and hagler weighed 159 pounds the day of the fight
What i meant is pretty evident. He showed a photo where golovkin looked huge next to hagler and i showed to him a photo with Tyson where Mike also looked smaller than GGG cause the angle of the camera. And i think that everybody knows that Tyson was bigger...
But being taller or having longer reach does not make you necessarily bigger. I think that golovkin has a little bigger Frame but there is noway that the difference was that big like this photo suggest, it was the angle and i proved it with the Tyson image
Prime for prime GGG v Hagler would have been awesome. A lot of votes for a KO which is a bit baffling. Neither of these is getting knocked out in their prime by any middleweight.
GGG is a bit overrated. He never faced the quality of opposition Marvelous Marvin Hagler faced in the 1970s and 1980s. The best fighter GGG has faced is Canelo fights he lost in my opinion. He could get stopped by Marvin who is arguably the greatest Middleweight of all time.
