The Islanders generated more opportunities in the third period, just as they did in Detroit. The Islanders were outshooting the Flames 11-6 in the third before Anders Lee scored to bring the Isles within one, knocking in a Brock Nelson rebound at the side of the net. Just under a minute later, Kyle Palmieri tied the game at 3-3, snapping a shot underneath Jacob Markstrom.
Third periods have been a strength for the Islanders this season, as the Isles have outscored their opponents 22-11 in the third period of games, tied with Buffalo for the most in the NHL. In the third period, Brock Nelson, Anders Lee and Mathew Barzal played on the same line, the first time that line has gotten significant play in a game. Those three have been the Islanders' top scorers this year. All three earned a point on Lee's goal in the third.
The third period rally forced the Islanders into overtime for the first time this season, and Noah Dobson won it for the Islanders on the power play, hammering a shot through a screen and past Markstrom. The Islanders found their way to their second third-period comeback victory, after the win against the Colorado Avalanche.
"That Colorado game was one of those games where, there's little moments throughout the year that can really change the course of the season," Barzal said. "I think that was one of them, and I think that played a little bit in tonight just knowing going into the third we hadn't had our best game and knowing we could still do it. That's what the locker room is like right now."
