New York Islanders 3 Takeaways from 3-1 Home Loss to Calgary Flames

The New York Islanders dropped the pre-John Tavares welcoming 3-1 to the Calgary Flames. What can we takeaway from the game?
After falling to the Calgary Flames 4-2 less than a week ago, the New York Islanders had a chance to return the favor as they welcomes the Flames to the Nassau Coliseum.
That game just six days ago, the New York Islanders didn’t wake up until the third period. Through 40 minutes the Islanders registered only seven shots on the Flames net.
The Islanders were passengers in that game and were lucky to only be down 2-1 after two periods. They couldn’t put up the same effort this time at home.
They didn’t, outshooting the Flames in both the second and the third period. But a power play that went 0-for-4 (more on that later) and a few weak goals from a typically solid Robin Lehner is what sealed the ‘L’ for the Islanders.
(Do yourself a favor, don’t look at the standings after the game. You won’t like it too much.)
