Agreed.Im hoping Golovkin gets a big fight should he beat Proksa. When you can it as hard as he can, he has a chance against any middleweight in the world. He's not as good as some people make him out to be, he's slow of hand and foot and he doesn't have a great work rate. I do think the likes of Martinez and possibly pirog would be too quick and skillful for him, but GGG's got the potential to be in some cracking fights with the likes of Martinez, the Geale-Sturm winner (if its Geale ) or Chavez.
In fact I don't even think he'll really dominate this fight either, though I do think he'll nail an eye-catching stoppage at some point in the mid-to-late rounds. I know the Kerry Hope fiasco has really put a dent in Proksa's standing, but his performances against Sylvester and Navascues were good enough to suggest - to me anyways - that he'll give GGG a decent degree of bother for a certain amount of time.
Golovkin doesn't throw much in combination, and for the most part he leads with wide roundhouse-hooks while often looking pretty vulnerable to being countered. He displays some nice defensive moves here and there, but generally not when he's forced to really pressure his man like he probably will be here. Thus I think it might be pretty back and forth in the early going as Golovkin attempts to find his rhythm and gives Proksa ample opportunity to counter. Hope was a fellow southpaw and generally made that fight even messier than it otherwise would have been, stylistically he's more difficult for Proksa than a dude like Golovkin in my opinion, but obviously the salient point is that Golovkin is just a hell of a lot better than Hope is(sorry Bryn).
Ultimately though I think Golovkin will get to him. GGG's power is usually sustained for the duration of a fight, and with the Pole not exactly being the bastion of great defense and usually leaving his chin hanging I think it's only a matter of time before he gets clocked cleanly.
