Here's my roster
FORWARDS
Artturi Lehkonen - Aleksander Barkov - Mikko Rantanen
Lehkonen and Rantanen are used to playing together, and Barkov has to be the #1. I think this could be a pretty good shutdown and scoring line overall.
Teuvo Teräväinen - Sebastian Aho - Roope Hintz
The old Carolina connection returns. I think the speed of Hintz is a good fit with these two on the wing.
Eetu Luostarinen - Anton Lundell - Kaapo Kakko
Luostarinen and Lundell play together, so they're an easy fit, and with Kakko I think this could be a pretty good second shut-down line, which this team will need given their defense.
Matias Maccelli - Mikael Granlund - Jesperi Kotkaniemi
Not a traditional 4th line, but rather a secondary scoring line. These are the guys you start purely in the offensive zone while lines 1 and 3 get all the defensive zone starts.
Erik Haula
There were a few guys I could have put here, but I like Haula's experience and versatility.
DEFENCE
Miro Heiskanen - Henri Jokiharju
I expect Heiskanen will be playing about 30 minutes a game, so Jokiharju is mostly a placeholder, and I expect to see Ristolainen here as well. That being said, statistically, Jokiharju has been one of the better defensemen listed here, but that's not saying much.
Esa Lindell - Juuso Välimäki
This is the closest I could get to a shut-down pair. It's a shame Lindell hasn't been playing better.
Niko Mikkola - Rasmus Ristolainen
Big, bruising bottom pair, altought I'm not sure how much I trust them.
Olli Määttä
I considered Urho Vaakanainen from Anaheim here, but I decided to go with Määttä's experience instead.
GOAL
Juuse Saros
The obvious starter. How for Finland goes in the tournament will mostly be on Saros' shoulders.
Ukko-Pekka Luukkonen
The clear #2. He's been up and down, but still good enough to be on the team.
Justus Annunen
He hasn't been consistently amazing this season, but when he's on his game he's nearly unbeatable. That plus he's a young guy who could be a mainstay on future national rosters.
