I know that this is a troll thread, but I think that Golovkin would be competitive with many if not most of the past greats. He'd make them work for the win, and I think he might just get a few wins himself.
GGG is unbeatable im telling you, the way he cuts the ring off and shifts is a thing of beauty. Even in the Olympics when he fought Dirrell who is suppose to be slick he gave him the business [YT]2COIu28PCKA[/YT]
never seen a fighter with GiGi's attributes before. he can cut off the ring perfectly, he has a great jab, his defense is pretty good, and he's an aggressive counter-puncher, he also hits like a heavyweight. GiGi is a h2h monster i think he beats a lot of past middleweights
