Manninen is an interesting case this year and I'd say a big mystery. He might look worse than we are used to with this strange season he has had and if that is the case, it will be interesting to see can he regain his form after he gets some games with team Finland. If he's a lot worse than expected now, that line won't work and that will be a problem going forward. It will be interesting to see Manninen in this EHT tournament. I think that we'll see quickly where Manninen's form is at.
I'd say that it's safer bet to say that Suomela is our #1 center at the moment. Hopefully we'll get at least one more good winger for Suomela's line from the NHL.
Suomela + Kapanen in the same line has been good so far though, but that line did have MaG as a 3rd piece. Personally I wouldn't do the full UFA thing yet. I assume that Jalonen will continue to experiment MaG + Suomela + Kappy line when this EHT tournament starts and if that line continues to be good, he won't break it, unless Rantanen joins. We've also seen Manninen + Hartikainen in the past perform very well without MaG.
I would keep Armia (7+7 in 43 NHL games) out of top-6 if possible. Big part of Armia's offensive production came at the end of the season (the hat trick). He goes on these huge cold streaks and that's been the case for 2 seasons in the NHL now (28 points in 101 games). In the NT we probably just got lucky with him last season that he was surprisingly productive. Might as well put Pesonen into top-6 instead of Armia. I love Armia as a bottom-6 player though.
