You have to say Finland was stacked for this tournament. Former NHLers and top KHL plyers.
It was an incredible roster for "Euro tournament". I feel like something like 10-14 of those players could be in the NHL right now. Most of them in smaller roles, but in active line up and playing.
To me these players in the first list could quite obviously be in the NHL. Some of them just came from there. Few have never been in the NHL and might still go there to give it a go. Many of these players didn't exactly get kicked out of the NHL, they just were offered the league minimum or wouldn't get to play a full season, so they wanted a change in scenery. Some of them wanted a 1-way contract only:
-----------------
Manninen - Could easily be an NHL player now. NHL has turned into a league where smaller, fast enough, skilled players can excell.
Björninen - His face off ability is out of this world and he can do other things as well. Those things are valued in the NHL. When Jukka Jalonen gets to be an NHL head coach, Björninen will be in his NHL team. Just watch me being right about this one.
Lehtonen - Just came from the NHL. Could've had a long career in the NHL, but gets paid NHL salary in the KHL probably with low taxes as well.
Komarov - Just came from the NHL. NYI head coach kind of wanted Komarov to stay. Komarov didn't like when they sent him into AHL if I remember right. He would've got to play more NHL games later this season despite of being sent into the AHL, but as a veteran he was tired of that and he got good enough offer from the KHL, plus he wanted to play in the Olympics with NHL players or without and it would've been hard to select him into Jalonen's team if he wasn't getting active minutes somewhere outside the AHL.
Vatanen - Just came from the NHL. I feel like he goes back to NHL next season.
Hartikainen - He gets paid far more in the KHL than NHL's minimum salary. He just has no reason to go to NHL and he has a legend status in his UFA team, so he is like very much attached to that team.
Säteri - He wasn't given a proper chance in the NHL. 8-9 games played and 4-4 win-loss record. Some players require luck to get that opportunity to show what they are made of. He didn't get that opportunity really. It is very similar to M. Aaltonen with that.
Filppula - Just came from the NHL. Could've stayed there for 1-2 more season with a 1 way contract I feel but money was not his priority.
Then in the second list these guys aren't as obvious to me, but I feel like they could maybe also be good in NHL at the moment:
--------------------
Ohtamaa - He's just a very good stay at home D. I don't see why he couldn't be an NHL player. He's known for turning down some very rich KHL contracts because he likes to stay in Finland and obviously if he stays in Finland he is season after season one of the best players of Liiga. Money is not his priority. He just gets home sick fast.
M. Aaltonen - I don't think that he was given a proper chance in the NHL and Leafs. He was just buried in to the AHL because Toronto had a rather good bunch of forwards.
Kaski - He was just a reserve, but I'll mention him anyways. It was his own choice to come back from NA and I feel like he could've been something in the NHL, even a star.
Olkinuora - I feel like there are worse goalies than him in the NHL currently
Ma. Granlund - He was a borderline NHL player before he went to the KHL, but I feel like he could've stayed there longer if he wanted as a 4th liner. Not sure if 1-way contract was realism for him but with a 2-way contract he would've got many NHL games each season.
Iiro Pakarinen - Nothing has changed from his NHL days. He could've continued to be a 4th line grinder there maybe. The currrent 4th line wingers in NHL in general aren't much better than him, if at all. 4th lines just tend to be treated like trash and given the league minimum wages and 2-way contracts only. He was in that kind of situation there.
Saku Mäenalanen - It was surprising when he left the NHL He played 34 games for Carolina in the 2018-2019 season and he left NHL right after that season. I feel like it was as surprising as Kaski abandoning or pausing his NHL career. Jokerit probably gave Mäenalanen a contract that matched NHL's minimum salary plus the advantage of getting to live in his home country are good perks.
I'm sure I missed a few. This team was loaded with good players!
