My quick impressions:
The first line was good and Vesalainen/Ikonen did show off their skill. Nyman was fine but did fail to capitalize on some plays that he should have scored on. One problem this line did have was a failure to establish a net front presence which was especially obvious in the gold medal game. Furthermore they often tried to be too fancy, especially on the power play later in the tournament, instead of going for the safe play.
Our 2018 draft eligibles impressed me and showed off nice skating, puck handling and passing. If they continue to develop the 2018 draft might not be completely devoid of talent on our part.
With regards to our defence our first pairing was impressive and there isn't really anything more to say that hasn't already been said, and then there wasn't much else. Especially Teräväinen was frustrating to watch, he failed to cover his man in front of the net on multiple occasions and often carried the puck into an opposing player leading to turnovers. Räsänens poor skating was also exploited several times.
Overall I'd say the tournament went quite well and the result was satisfactory, especially considering the players we were missing. We just ran into a better team in the final.
