I actually like the idea of rotating Kassian and Chiasson for the top line.
Kassian does a better job in the trenches, opening up space for McDrai to go to work; while Chiasson has smoother hands in front of the net and possesses a better shot, and is able to finish off plays.
I also thought Lucic had a strong game. Personally I like him and Khaira playing together. Chiasson (or even Pulju) seem like the natural answer to round off this line.
This leaves you to drown Rieder and Brodziak in defensive minutes and usage, but I think they can handle it.
Draisaitl-McDavid-Kassian
Rattie-RNH-Pulju
Lucic-Khaira-Chiasson
Spooner-Brodziak-Rieder
