We'll have to see where all the pieces fit, but I think we're looking at something like this:
Marchand - Bergeron - Smith
Hall - Krejci - Pastrnak
Ritchie - Coyle - DeBrusk
Frederic - Lazar - Wagner
Kuraly, Kuhlman
Grzelyck - McAvoy
Reilly - Carlo
Lauzon/Zboril - Miller/Clifton
I think to start, I'd leave Smith with Bergy and Marchand. That line has been working recently and Smith hasn't looked out of place. Pasta's slumped but I think would be a great fit with Hall. Hall leads the league in high danger passes, Pasta seems like an ideal guy to be on the receiving end and pulling the trigger. Probably can't go wrong either way, but I'm intrigued by Hall and Pasta together. Next up is sorting out the bottom-6. Sweeney said he'll leave it up to Butch but thinks DeBrusk gets kicked over to the right at least to start. Then they have about a billion guys they could plug on the 4th line, just have to find the right combination.
On defense, I think Reilly lets them pair Grz and McAvoy together when both are healthy. That duo has been dominant when paired together. Reilly could be a good transition, puck mover to put with Carlo. That leaves sorting out who plays on the bottom pairing. Ideally Miller, but his knee could explode at any moment. I think at this point I have Zboril ahead of Lauzon but now that's a real competition. Just hope they get healthy back here and we see it. It sounds like McAvoy will return tomorrow night, which is great. Grz is day-to-day so hopefully he's not out too long. That leaves Carlo who last I heard was still week-to-week.
