Just like Kakko, in a year or two he'll be fine.
I'd actually say Kakko being pretty mediocre is the significantly bigger surprise. Coming off what he did at the worlds, and against men in Europe, combined with an obvious size and physical maturity advantage.
With Jack Hughes, it was always going to be a question of whether his speed would let him survive in the NHL as a really small, physically immature kid. I think we've got some clarity on that, as he's struggled. Really just a matter of how long it'll take for him to get to where he needs to be physically...and it's still up in the air if he'll ever get to a place where he can thrive as a fixture at Center rather than as a Winger long-term. As well as how long it'll take for his game to mature and round itself out.
With Kakko...i think he will be just fine in the end, and i guess at times we start to establish too high a standard for kids coming straight out of the draft into the best league on the planet in an 82 game grind. It's still kinda surprising that he hasn't been more prolific though. There's nothing
obviously deficient holding him back like there is with Hughes size/strength/maturity.
