I think Jenner-Dubi-Cam and Calvert-Sedlak-Hannikainen are pretty straightforward. I'm not a huge fan of pairing Jenner and Dubinsky, but Atkinson adds some much-needed speed and skill to the line. If PLD shows he belongs, I might like to see him switch with Dubi. The fourth line is a classic fourth line with three defensively responsible players; Motte can draw in for any of the three positions. I don't really want Milano sitting in the press box and occasionally playing fourth-line minutes, but he'd be the first call-up if any of the top-9 wings get hurt.
I go back and forth on whether I'd rather see Foligno with Panarin-Wennberg or Dubois-Bjorkstrand. Foligno's probably the team's best possession forward, so it makes sense to put him with the best playmaker in Wennberg and sniper in Panarin, but also, that leaves Anderson on his off wing as the most experienced player on that third line. Anderson can bring a lot of the same skills as Foligno and while he sometimes disappears, he's also got, perhaps more than any other Jackets forward, an ability to completely dominate a game in every facet when everything's clicking for him (his game on 11/29 against the Lightning was maybe the best game from any Blue Jacket over the last several seasons).
So I think I'd go:
Panarin-Wennberg-Anderson
Jenner-Dubinsky-Atkinson
Foligno-Dubois-Bjorkstrand
Calvert-Sedlak-Hannikainen
But for the sake of getting weird, I might also like:
Panarin-Foligno-Atkinson
Anderson-Wennberg-Bjorkstrand
Dubois-Dubinsky-Milano
Jenner-Sedlak-Calvert
This has a few major problems, primarily Nick Foligno, First-Line Center, but I like the idea of Panarin and Atkinson on the same line, and Foligno's a defensively responsible possession driver who's capable of playing the facilitator role. On the second line, Bjorkstrand was at his absolute best in Portland when he was able to find soft spots in the defense with Paul Bittner wreaking havoc on the opposite wing, so I'd like Anderson to replicate that dynamic as closely as possible. Then the third line I'm basically just guessing, since I don't really have a handle on how PLD or Milano would fit into the Jackets' offense. They'd probably benefit from having Dubi as something of a babysitter, I guess. Finally, Jenner adds some scoring punch to that fourth line that it lacks as Calvert-Sedlak-Hannikainen, and I'd probably also have him play the Sam Gagner net front role on the PP, plus setting screens for Werenski point shots.
