Since Heiskanen is out and with these recent trades with Granny & Rantanen I'd go with something like this.
Teräväinen-Barkov-Laine
Lehkonen-Aho-Rantanen
Kakko-Hintz-Granny
Luostarinen-Lundell-Armia
13th forward (Haula will not recover in time right?):
Kotkaniemi/Tolvanen
----------------
For PP:
Do you guys see a problem if we use one 5 forward PP unit or which defenders would you put on our PP unit(s)? I'm guessing Ristolainen would be the best D option for PP as much as I hate to say it ...
But here are my suggestions for 5 forward units:
Teräväinen - Kakko (mask) - Barkov
Laine - Granny
----------------
Aho - Lehkonen (mask) - Rantanen
Hintz - Lundell
Hintz seems to operate from same spot as Laine on the PP, so I don't want them to be in the same unit. Rantanen changes positions on the right side. Need them one timers. Lundell changes positions a lot and also would do a lot of masking duty here with Lehkonen.
----------------
For the PK, this leaves Luostarinen & Armia pair. Some players from the PP units will do double duty on special team moments.
Point producing defenders... Well, the best one is Lindell and that says a lot, but I'm not putting him to a PP unit, because he has so big role with PK. Big minutes for him.
