I've been a boxing fan for 19 years, should I be ashamed that I have no idea who either of these two guys are?
Golovkin is an excellent boxer puncher. His style has been compared to Kosta Tzuyu. He's actually a small middleweight but I consider him p4p the biggest puncher in the game. He fights going forward but slips a lot of punches and counters more than he leads. He's doesn't have fast hands but his timing is top notch. Proksa has a reflex based, hands down defence somewhat reminiscent of (but obviously not as good as) Roy Jones Junior. He's also a small middleweight. He throws a lot of punches from awkward angles but doesn't look as polished as Golovkin. His style may confuse Golovkin early in the fight. This is a quality match up. Be sure to watch it.
You can have a similar style to someone without be anywhere near as good as them. The Polish baiting is really boring too. Find a new angle. Your performance act is ****.
Dumb Man!:deal Everyone has an off night. Proksa learned from that, came back in a rematch & beat down Hope bigtime. Time to move on now to bigger & better things...
