The Islanders couldn't overcome the depth of the Hurricanes
The New York Islanders did a good job shutting down certain players on the Hurricanes. Although they had their moments, guys like Jake Guentzel and Sebastian Aho were not as threatening as we've become used to seeing them.
However, there was too much depth on the Hurricanes for the Islanders to handle. The fact that they did well against some players kept them from stopping others.
One player in particular, Seth Jarvis, was huge for Carolina against New York. He had seven points in the five games played during this series. He had more points than anyone on either side.
With the aforementioned lack of scoring that the Islanders have, it is hard for them to overcome all of the depth that the Hurricanes have.
Now, if Jarvis gets shut down by the New York Rangers in the second round, you'd think that the other big boys get going. The Islanders don't have a similar luxury.
