roslovic isn't ready to play in nhl this year and playing him on the second line would be cruel to him and wheeler. sgarbossa has a better chance of playing on this team next year then petan . also a couple of healthy scratches are not sending mathias to the press box.
I think you and I are writing pretty much the same thing. Assuming Connor is ready which I think he is. I see it our top 9 is almost written in stone.
C - Scheifele, Little, Lowry
W - Wheeler, Ehlers, Laine, MP, Armia & Connor
The 4th line will be some combination of Matthias-Copp-Dano with Tanev and Sgarbossa as PB guys. Then I'd let the more skilled guys on ELC's (Petan & Roslovic) get top 6 minutes on the Moose and be called up to plug for injuries in the Jets middle 6 as needed.
