He needs some work. Way too much is being made too early and while talent-power is obvious he hasn't faced anything remotely close to the neighborhood of a Martinez. I see him a bit one deminsional thus far and the movement he faced in a punch prone Rosado (one out of panic and preservation mostly)...and the movement a Martinez brings (shifting you into your own momentum and countering) is nothing similiar. Rosado showed mass balls but he was also badly hurt in more than a few of his recent fights. Golovkin might...may...coulda...woulda all he wants but you have to deal with what is actually happening. Golovkins defense is apparently his offence largely, that head is prone to left hooks among other things. HBO is determined to put a cape and theme music to him this early but he is no Chavez sr or Tyson, he's a guy who is 30 yrs old and has yet to complete 10 rounds with a strong fan friendly attack and solid potential, but let him walk before he runs.
