People complaining about Marjamäki's playstyle really should keep in mind that playstyle is, in large part, also dictated by the material available. A team like this - the player's skill levels being what they are - simply is and was grossly incapable of playing fresh, active, offensively creative hockey, no matter how much you whined about it and wanted to see them try it.
Well, in fact they did, a couple of times - in the Canada game and now in the last period vs. Russia. Well, if we wish to be pedantic, I can't say these games were lost because of it - but it sure as heck didn't help them win. And given how you guys weren't happy either way (though Nikita Kucherov sure was), it seriously feels like one of those "damned if you do, damned if you don't" situations. At the very least, playing more active hockey would have required a better goalie than either Säteri or Korpisalo proved to be.
Ultimately, the playstyle and the game plan for this tournament was just fine, once we accept the realities of the material available. I personally felt far more frustrated with the Nose last year, and how kept that squad in far too short a leash.
But that's not to say this was the best they could have done, no matter what. What really did us in was not the "anti-hockey" - it was special teams. Our PK was quite mediocre, and our PP pretty damn teethless. Apart from Aho and Rantanen, we didn't really have world class assets to put out there, and the somewhat serviceable ones were in short supply. For example, as reliable as a workhorse like Pyörälä is, in most teams he's part of, he would have no business being part of the PP units.
Maybe what they could have done - and this is part hindsight, so don't go lynching anybody - was strike a balance between conservative, defense first 5-on-5 game and having more talent that could perhaps not do much more on ES except play it safe, but who would then have unique abilities that would be assets on special teams. Simply put, shooters. We didn't get Laine, but Late could've picked Palola, and, well, Pulkkinen was available too.
In a nutshell, accept the realities of the material available and play boring but effective "anti"-hockey when need be, but when you get those opportunities to do more than that, make sure you have at least some talent out there who can.
Now, then. However. Even if demanding a more active playstyle was a complete pipe dream and, frankly, those who demanded it had no idea what they were wishing for, I'm not sure I can say we can hope to keep up with the realities of modern hockey even by playing defense first - at least with our currently established names. Guys like Kemppainen, Pyörälä, Kukkonen, Järvinen, Jaakola, etc, may be slowly becoming dead weight even if we accept that we can't play more active hockey with them. Perhaps one of the amends Marjamäki should make for next year is starting to look for players who can. Weed out a new core from that mass in Europe - one that is more mobile. (Even if it costs us some more EHT games and gives a bunch of Karjala Caps some more grey hairs.) The aim would not be finding players who can be completely unleashed, but the kind of players who can stick to our current brand of hockey - and at least be effective with it.
