From his draft year to his post-draft year, his points/game went up. This year, his goals/game is the highest it's been since he turned pro. I think you're getting yourself too wrapped up in his assist totals this year, which appears to be both an outlier and a mirage, givens that he appears to be Finland's best playmaker this far (along with Barkov).
I'm not saying that you have no right to be worried, but I keep hearing from people--not just you--about how concerning his numbers are this year just because he doesn't have many assists. I don't think it's that big a deal.
What is this based on?
And like I said, yes his goals/game is the best it's been since he turned pro, but again, over a 48 game season it equates to one more goal than his draft year. I'm not even looking at assists, I agree with you on goals being the biggest issue. All I'm saying is...yes, it is a small sample size but one goal improvement over 48 games two years later isn't the progression I look for (improved last year and then appearing to have regression a bit from last year to this year).
The upside is still tantilizing and it appears some weaknesses are being rounded out but not quite as much as I would've hoped after 2 years of development.
