While I'll admit that I'm not great at picking up on the match ups, I seem to recall Gelinas getting some shifts against the Sedins.
Gelinas and Larsson saw mostly Higgins-Santorelli-Kassian, not pushovers at all but not on the same level as what Greene and Fayne were seeing for the most part with the Sedins and Kesler. Gelinas saw the Sedins and Kesler well less than any other D, even Larsson, so it must have been an odd shift.
Greene and Fayne saw 41.7% and 33.4% of the Devils even strength ice time respectively. Gelinas and Larsson saw 24.7% and 31.4% of the Devils even strength ice time respectively. Gelinas had the least even strength ice time for the Devils D but was on for 43.1% of the Devils PP time - rightfully so.
Gelinas had the 2nd most favorable zone starts for any Devil tonight, and best for a D, with a O/DSt% of 70%. To put that into perspective the Devils other D: Zidlicky: 54.5%, Larsson: 54.5%, Volchenkov 50%, Fayne 42.9%, and Greene 27.3%. Greene and Fayne only had 3 offensive zone starts (this all being off faceoffs at EV) each. Gelinas and Larsson had 7 and 6 offensive zone starts each.
Gotta give credit to DeBoer, he put Gelinas in a place to succeed and Gelinas took advantage of it. Incase anyone is wondering, O/DSt% = offensive zone starts at EV/ (offensive + defensive zone starts at EV). The higher the percentage the more favorable the zone starts.
As I said before, I'm very interested to see what happens when Sal comes back. Either Gelinas gets sent back down or Harrold is put on waivers. I'm leaning towards the latter. I don't think they would have played Gelinas tonight if he wasn't going to get a legitimate shot to stay with the team. On the other hand, you'd rather have Gelinas get regular playing time in Albany than having him on the bench very third game or so.
I really have no clue what they are going to do, or really what they should do. Like earlier today, I noted that Salvador and Volchenkov get grief (even misplaced by me in the past) due to their contracts, but they've both been solid this year, especially as key anchors on the PK. I don't think you can take them out unless Volchenkov's 5v5 play really, really drops off.
I'd actually like to see the Greene and Fayne pairing get a solid run of games. I feel like that's a pair that can do some heavy lifting matchup wise and take some of the burden off the other D.
Larsson had a solid game and he deserves and needs to be playing regularly so I want him to stay in the line up. We all know I'm not a huge fan of Zidlicky - moreso because I think Gelinas could make the jump, playing on the 3rd pair and getting PP minutes, but Zidlicky is in to stay even though he's a rollercoaster of giveth and taketh.
I will say this, if he's not waived, Harrold should absolutely be the 7th D and only play due to injury or if one of the other 6 really falls of form. Even if they waived Harrold, I'd hate to see any of Fayne, Larsson, or Gelinas as the 7th D. Really have to think that if they want Gelinas on the roster they'll have to move someone and I think Fayne would be the most likely to move unfortunately.
