No, but it makes you question just how good his NHL career will end up being.
Barkov is out there competing every shift, making things happen, and is being trusted to be the most important player for his team as a young 17 year old and 19 year old Armia is most likely floating around waiting for an opportunity to pounce and subsequently turn the puck over.
They're fundamentally different players, but it's still disconcerting to see the gap between the two.
There's a reason Barkov is in top 5 discussion and Armia was a mid-first pick. It's because Barkov is a more impressive prospect. I don't really find it all that disconcerting. That there are better players than Armia doesn't mean Armia won't pan out.
I'd also bet good money Armia would look much better if he actually had a linemate who could set him up considering he's definitely a shoot-first kind of player. In the WJCs, for instance, he's been a significant player for Finland, only being outscored by Granlund and Pulkinen last year (5+2 in 7 games), and I think you'd be hard-pressed to find a Fin who wouldn't slot him on their top line this year. But he's playing with Michael freaking Ryan.
Armia's game has flaws for sure. I'm not arguing otherwise. But I don't think there's a single Sabres fan that expects him to be the kind of player who carries an offense or, like, PKs. I expect him to be an effective goal-scorer and a strong presence on the forecheck, and I haven't seen anything from so far him that indicates he won't be able to do that.
