I know probably 2 maybe 3 people will see this post way down here, and half of those will be on accident. But I had to see if anyone else was watching this guy box? He could be the scariest boxer I have ever seen in all my years of watching. You watch him throw punches and they look solid, but not near hard shots or actual punishing shots, but then you watch the guys he hits. He taps a guy with a jab a nd the guys head goes flying back and his eye starts swelling shut right away. It's like his fists are made of steel. I have been trying to think of a guy who he boxes like for several days now, and I just can't. Closest I can think of is a young "Iron" Mike Tyson when he was young and hungry and had a good trainer and was a good boxer but just mowed people down. But Golovkin isn't really that similar, he fights with a much different style than that bobbing weaving buzzsaw of Tyson, and kind of just stands there and punches but somehow slips punches too. But the way his oponents are just scared of him is like a young Tyson. You can actually see their fear of him.
He is still young like a Cannelo Alverez, so may never pan out into an all time great or anything. And even though he has a couple titles now, once he steps up the level of competition maybe they will stop being terrified of him in the ring. But right now he is by far my favorite boxer, and I can't wait to see what comes (hopefully relatively free of fixes).
Actually the best comparison I can think of may be the fictional Ivan Drago. But this guy is real, hits like a truck, and still won something like 340/345 amatuer matches where they wear headgear so he has more than just power.
