The current IFK Helsinki isn't something I'd describe as "a very good team", to be perfectly honest. And the only wins being in OT/SO for clubs of a league that should be a clear step above the others is rather disappointing at least to me.
As for Tappara...
Tappara's Liiga preseason record so far:
vs Ilves 5-1 w
vs HIFK 4-1 w
vs Sport 6-3 w
Undefeated, every single match absolutely dominant. The Salzburg game isn't the only one I am going by. I guess we'll see how Wolfsburg is going to do against them.
Here's some preliminary Liiga team(ones that participate in CHL) power level estimations using something called Game Score in case some of them are unfamiliar, with the first number being the amount of players in top 80(f)/50(d) and then total Game Score factor something:
Forwards:
Tappara 10 (14,8)
JYP 8 (11,6)
TPS 7 (11,2)
HIFK 6 (8,0)
KalPa 5 (4,9)
Defensemen:
Tappara 6 (7,4)
HIFK 6 (5,9)
TPS 3 (4,6)
JYP 3 (3,8)
KalPa 2 (3,0)
Goalies unfinished but apparently the only CHL teams in the top 5 would be something like:
Tappara
HIFK
JYP
