The Islanders found themselves behind early on Sunday evening, as Anton Lundell opened the scoring 39 seconds in, banking a shot off Semyon Varlamov's arm from a sharp angle.
The Panthers took a 2-0 lead midway through the period, as Eetu Luostarinen's shot deflected off Sebastian Aho's stick and past Varlamov at 9:13. Preceding the play, Noah Dobson took a puck to the throat, which took him out of the play. There was brief concern for Dobson, but the defenseman returned later in the period.
Sunday's game had a different cadence and game script. After being the aggressor on Saturday in Tampa, the Islanders spent a majority of the game at five-on-five in their own zone, getting outshot by the Panthers 24-13 at even strength. The secondary effect was that the Islanders were unable to sustain offensive zone time and generate quality chances, being held to one high danger chance at five-on-five, including none through the first two periods, per Natural Stat Trick.
"Five on five we just got to find a way to create a little bit more open ice in the offensive zone and deliver the puck," Lee said. "We had plenty of shots in previous games that created a lot of zone time and I think when we stick to that and are able to generate that it pays off for us."
Lee's first power-play goal brought the Islanders within one, but Lomberg jumped on a loose puck at the left dot and quickly slapped it by Varlamov at 2:56 of the third period. Lee's second power-play marker brought the Isles within one, but that's as close as they'd come.
