So, with NSH out, we can potentially add a goalie and a forward, possibly even two.
The goalie situation is pointless to speculate with, either we get one of Rinne/Saros or not.
With skaters, it's more interesting. Technically adding any two of Niemi/Tolvanen/Salomäki would be a big boost to our offense, but we'd then only have 7 D to run with for the rest of the tournament. It's not a huge risk, since losing two d-men in one tourney is relatively unusual, but still.
Personally I'd probably add the two forwards.
Tolvanen-Granlund-Rantanen
Savinainen-Aho-Teräväinen
Pesonen-Suomela-Kapanen
Mäenalanen-Niemi-Anttila
Some might say it's pointless to add Eeli, since he hasn't played for a month, but let's keep in mind that he's been actively practicing this entire time.
