He is too young to conclude anything, Oiler fans are willing to wait and see.
Comparing him to Yakupov, who didn't know how to play the game of hockey because no one bothered to teach him, tells me you don't know much about Puljujarvi.
Not even close. Puljujarvi does many things at an NHL level. The issue is the instinct to the net and being able to score seems to be some of those things he doesn't do at an NHL level. In the NHL if you have to stop and think about what to do, you're not going to do it.
This year is a real danger for him, he should be acclimated to North American hockey by now, but if he's not given AHL development time to get that muscle memory to do things on offense that lead to goals, he's going to end up a 3rd line checking forward and a good one, but with limited offense.
Reminds me way more of a better version of Magnus Paajarvi-Svensson. Kind of funny that Hitch messed up MPS by not giving him NHL time and Hitch is also messing up Puljujarvi by not giving him AHL time.
A smart team would nab him and give him AHL time the rest of the way and keep him in North America this summer to train, then he could make an NHL impact at some point next season.
