I think we will see the following line combos:
Verhaege (Rodrigues) - Barkov - Reinhart
Samoskevich (Marchand, Rodrigues) - Bennett - Tkachuk
Luostarinen - Lundell - Marchand (Rodrigues, Samoskevich, Boqvist)
Rodrigues (Gadjovich) - Nosek (Sturm) - Greer (Boqvist, Puljujärvi)
Forsling - Ekblad
Mikkola - Jones
Schmidt (Megna) - Kulikov (Balinskis)
PoMo loves Rodrigues as his Swiss army knife. He is the most versatile player (behind Barky and Reino) who can play with anybody on any forward position, is a righty, can be clutch, is defensively aware, hits and is decent at FOs. Before we loose him, clearly Luosty gets traded next year.
Megna has been a very nice surprise over the last games, looking better than Björnfot and Balinskis and better suited for hard fought PO times. I believe he is just about to win himself a job for the POs as a 7th Dman with his size, physicality and decent outlet passing.
If Puljujärvi continues to use his body as much as over the last games, he might get a real shot next year.
We will see a lot of rotation on the 4th line, as PoMo did last year, keeping them fresh to be able to pound the opposing team game after game.
