I just don't agree with your assessment on players. Barkov is good, but I think Zibanejad is close to him. There isn't that much to separate them in terms of production and both are obviously great two way players. I think Aho is on the same level as both of them, but so is Pettersson, if you look at all seasons he has played besides this one. I actually think Pettersson is the most skillful forward from Sweden and Finland combined.
And to say we don't match Laines firepower is disingenuous. Forsberg is by every metric a better offensive player than Laine right now, but I agree that Laine has better raw tools. But if you think Aho is much better than the streaky Pettersson, Forsberg has to be considered better than Laine. Same thing goes for Nylander really.
The comment that grinds my gears the most is the one about defencemen though. I think Dahlin has been as good as Hedman for two months now and expect him to hit prime Hedman/Karlsson levels in 2026. Dahlin is the single player in the NHL you underrate the most. He is one of the best passers and puck movers in the world, already, and controls games for fun. I know that I am higher on Dahlin than most, but I would take him over every single player in the world over the next 10 years, besides McDavid. He's that good. To say we won't have superstar defencemen is just weird. Dahlin is better than Hedman at the same age. Adam Boqvist and Rasmus Sandin are just as talented as Klingberg/OEL. Edvinsson is one of the worlds best young non-NHL defencemen and a considered a way bigger talent than the likes of Ekholm, Klingberg, OEL, Lindholm, Brodin at the same age. He is nowhere near Dahlin but still a really, really high end prospect, and I can't see him not surpass Heiskanen.
Lets look at 2000s born first round defencemen. Sweden have Rasmus Dahlin, Adam Boqvist, Rasmus Sandin, Nils Lundqvist, Phillip Broberg, Tobias Björnfot and Simon Edvinsson. No country in the world matches that. Our 2000s born defensive core is arguably better than anyone we have ever had.
