How much longer will Gennady Golovkin be on top of his game?

He takes great care of himself. He doesn't get hit as much as people believe. He's hittable, but he's never sustained huge amounts of damage in a fight. So I think he can definitely go on for another 2-3 years at least, probably more.

Hard to say, he is 32 and fights four times a year but then again he takes no punishment in any of his fight and they all finish quick. His style might let his prime go a little longer as he doesn't rely on his reflexes as much as other boxers, just uses his power and good fundamentals. Im hoping we get a good solid 3 years of his prime against top level competition.

well.....its hard to say, he has great power and we all know it's going to take him a long way, definelty in the division he's in at the moment(middleweight) but personally i couldnt give you exactly how long he be on "top" till i see him move up 168 and/or fight better opponents.
