You can only take 31 players to the bubble, and that includes goalies, so there will be cuts.
I'd expect to see this 31 player roster:
Burakovsky ---- Mackinnon ------ Rantanen
Landeskog -------- Kadri ---------- Nichuskin
Namestnikov --- Compher ------- Donskoi
Nieto ------------ Bellemare ------- Calvert
Jost -------------- Kamenev -------- O'Connor
Tynan ------------- Dries
Graves --------- Makar
Girard --------- Johnson
Zadorov ------- Cole
Barberio ------ Timmins
Connauton --- Byram
Grubauer
Francouz
Werner
Hutchinson
Cuts: MacDonald, Lindholm, Bowers, Wilson (IR)
Lindholm vs Connauton is a close call and could go either way. Bowers isn't quite ready for the NHL so I think Bednar would go with Tynan and Dries for their experience.
