Golovkin is not a one punch KO guy, He doesn't hit harder than Canelo or Lemieux

I been saying this for a while that GGG is not a one punch guy, he is a heavy handed guy with slow punches that breaks you down. But he doesn't have that shocking KO power that leaves guys with that what just hit me face? I think Peter Quillin hits harder, its just GGG has a granite chin and great at keeping distance and doesnt waste shots. Curtis Stevens who fought Golovkin and sparred Canelo even said that GGG isn't a hard puncher and Canelo hits much harder. David Lemiuex who fought GGG said that GGG isn't really a hard puncher and that he hits harder than him. https://www.youtube.com/watch?v=PaXTnHw9N5M I believe it, because he breaks guys down with smart pressure and doesn't let them breath, he is a slow methodical but very intelligent pressure fighter, he doesn't smother you like the traditional Maidanas, and other pressure fighters who have to get in real close. He doesn't have that one hitter quitter power, but he isn't a pillow puncher he just breaks guys down with pressure and punches solid shots but finishes you off after he fatigues you like most pressure fighters, but the reason people think he is a dominating power puncher is because he lands CLEAN shots. He doesn't waste punches which makes him similar to Julio Cesar chavez, Chavez was also a very methodical slow but intelligent pressure fighter he didn't waste punches and broke you down from mid range with body head combos.
