Islanders 6, Golden Knights 3: 3 Takeaways

ANOTHER GOALIE went down!
With the Golden Knights ahead 2-1 in the second period, Oscar Dansk left the game with an apparent injury. With Maxime Lagace stepping in to make his NHL debut, the wheels fell off for Vegas, as the Islanders scored five straight goals to take a 6-3 decision.
Vegas' record drops to 8-2-0.
Here are three immediate takeaways from tonight's game.

1. Dansk's exit changed momentum
Midway through the second period, the script in this game was pretty much the same as the previous five, all Vegas victories. The Golden Knights were ahead 2-1, and were riding another strong goaltending performance which nicely complemented a couple of timely goals.
It looked like it was another game the Golden Knights would win.
With 5:10 remaining in the second period, however, Islanders star John Tavares tied the score. And on the sequence, Oscar Dansk seemed to get banged up and exited the contest.
From there, Vegas lost all momentum. Within three minutes, Mathew Barzal made it 3-2 New York, and the Islanders rode the momentum the rest of the way en route to a 6-3 victory.

2. Lagace's debut
Miraculously, Maxime Lagace became the fourth goalie to suit up for the Golden Knights this season, in only the 10th game.
Even more miraculously, three of those four - Malcolm Subban, Dansk and Lagace - entered this season with a combined two games of NHL experience.
For Lagace, who arrived via free agency from the Dallas Stars' AHL affiliate over the summer, tonight was his NHL debut. Lagace allowed four goals on 11 shots. And as the Islanders surged in the second half of the game, it was not the level the Golden Knights needed to win.
With no word yet on Dansk's status, it's uncertain who'd start in goal against the New York Rangers tomorrow night.

3. Ran out of gas
Although a good amount of the storyline coming out of tonight's game will be how another Vegas goalie got hurt, and how the team's fortunes went down the drain when this happened on Monday, this was a team letdown.
In the early stages of play, the Golden Knights owned the puck and had the Islanders on their heels. At the same time, the Islanders were rolling later in the game and had Vegas on its heels.
The Islanders were buoyed by another standout performance by their captain, as John Tavares scored two goals and was named the game's first star a few hours after being named the entire NHL's first star for last week.
When the Golden Knights had the better of play, they couldn't land the knockout blow, despite having many chances against Jaroslav Halak while ahead 2-1. But Vegas couldn't push through. Which in a way, is very similar to the team's only prior loss, when the Detroit overcame a third period deficit and won 6-3.
On the bright side, the Golden Knights are still 8-2-0 and have led in every game they've played this season.
On the down side, Vegas will need a much better effort to avoid a second straight loss tomorrow night against the Rangers.
