Very interesting to maybe see a Archibald-Khaira-Kassian line or Koekkoek-Bear pairing for this series.
Rare to see combos that you haven't seen at all really before entering a playoff. No idea what to expect from these. (That forward line was speculated by someone in the media for game 1, forgot who)
Koekkoek didn't work well with Barrie or Larsson to my eye really, but Bear I think gives him a better chance to be Chicago Koekkoek.
EDIT: Aside from the last game for the D pairing, but also that's a nothing game.
