I'm a big fan of that second line, idk about the rest though.
Chiasson hasn't earned a top line spot at all, but Drai and Mcdavid should be able to succeed with anyone on their line, so I guess it's not gonna hurt too much.
That second line is what I've been asking for for a while. Kassian has the ability and speed to retrieve pucks and open up more room for Neal and Nuge, while also being skilled enough to cycle and chip in some points. Hopefully it looks as good on the ice as it does in my head.
Line 3 is Meh. 3 players I don't much care for at this point, but Khaira has been getting better. My ideal third line will be Nygard Haas Khaira.
Line 4 is okay. Haas on the wing might give him some more freedom to use his speed and drive the play, but he's probably going to only be getting 5-6 minutes. Maybe Cave can carry over the momentum from last game.
