The Islanders started the second period on the power play with 1:12 carried over from Lafferty's tripping penalty on Wahlstrom, but their discipline and structure unraveled from there. Though the first 30 minutes of play, the Islanders had allowed five unanswered goals which only made their late push that much more challenging as they responded with three of their own in the second half of the game.
"That's why we lost the game," Jordan Eberle said of going down 5-0. "You get down that many [goals], it's too hard to come back in this league. There were some defensive breakdowns by us. They're a good team over there. They've been capitalizing, look at the standings they've been doing well."
The Penguins flipped a switch and extended their lead 5-0 with three goals - including two on the power play - scored in the span of 3:55 in the middle frame. Fortunately, Barzal's goal late in the period cut the Islanders' deficit down 5-1 and softened Pittsburgh's skew for the period.
Pittsburgh began the scoring flurry as Nick Leddy went to the box for slashing at 4:09. The Pens power play went to work and converted at 4:26. Sorokin made the initial stop on Kris Letang's point shot, but was unable to detect the rebound, which was roofed in by Crosby.
"We have a pretty good first and you're down 2-0, the next goal becomes a pretty important goal," Trotz said. "If you make it 2-1, you're back in the game, they make it 3-0 and now the mountain looks pretty big. It is a tougher way to live, it's not impossible to come back and win games, but it takes a lot more from your bench. We're also a better four-line team when we roll them over and don't worry about who is up against anybody. We seem to have more success that way. When you're chasing it, you're giving it more to different people."
Not even a minute later, the Islanders returned to the kill in an uncharacteristic fashion as Scott Mayfield was whistled for cross checking at 5:30. Swift puck circulation from Pittsburgh's power play unit provided a tic-tac-toe sequence from McCann to Crosby to Rust for a 4-0 lead for the Pens.
Trotz subsequently pulled Sorokin in place of Varlamov, which marked the first goalie change the Islanders have had to implement this season.
At 8:21 Rust scored his second goal of the game. The Penguins forced a turnover as Varlamov attempted to pass the puck from behind the net. Guentzel out-muscled Ryan Pulock to gain possession and poor coverage from the Islanders exposed a wide-open spot in the slot for Rust to beat Varlamov.
