Re: Who looks more impressive: Gennady Golovkin or Sergey Kovalev?
Golovkin is far more proven and has been generating buzz ever since his amateur days.
Kovalev has only been known outside Russia for two years (and even then, only by a few people until last weekend) and simply doesn't have anywhere near the depth of resume Golovkin has - again, dating back to the AM's.
However, if you ask me whether it's just as likely Kovalev rules 175lbs with as iron a h2h fist as Golovkin is expected to rule 160lbs...then I'd say yes, absolutely. He looks as potentially dominant against everyone at his weight.
