I'll give this a shot for my first post here.
Hyman - Matthews - Marner
Marleau - Kadri - Kapanen
Kovalchuk - Nylander - Brown
Johnsson - Aaltonen - Gundstrom
Rielly - Hainsey
Gardiner - Zaitsev
Dermott - Borgman/Rosen
Andersen
Sparks
With the forward group I think it's about time Babs finally puts Matthews and Marner together on a line. Hyman can keep doing his role of doing the dirty work and creating space, as Marner sets Matthews up for goals. Kapanen has been continuously improving the past 2 seasons, and I think he'd be a great fit with his speed and skill, on a line with Marleau and Kadri. Nylander gets to play more sheltered minutes on the 3rd line, as he learns how to play C in the NHL. Signing Kovalchuk and playing him on the 3rd line also hopefully keeps him fresh throughout the season. The fourth line will already have chemistry together and should be really fun to watch.
As for the defencemen, Ideally I would have Hainsey on the 3rd pairing, while also being used on the PK, but I don't see that happening right now. Gardiner maybe gets traded at some point in the season, but I see him being on the team at the beginning. I'm hoping Zaitsev can rebound next year, as I found he struggled, especially in the playoffs. I like all 3 of Dermott, Borgman and Rosen, and am hoping they continue to improve and eventually move higher up in the lineup.
In nets, obviously Freddy returns as the starter and am hoping Sparks can win the backup job.
