The New York Islanders have taken a crucial step this season, clinching a spot in the 2019 Stanley Cup Playoffs. But it’s just a step. The have their work cut out for them as they try to capitalize on their first postseason appearance since 2016 and make a run at the Stanley Cup.



Defense and goaltending have defined the 2018-19 Islanders, who have exceeded expectations under first-year general manager Lou Lamoriello, head coach Barry Trotz and the entire regime. But while the defensive-minded focus has led to regular season success, the question becomes whether the two pillars are enough to sustain them through the playoffs.



Much of the Islanders’ success this season can be attributed to the new coaching staff. Trotz has helped transform the Islanders’ defense, which had its gaps over the years. Then, the two goaltending gurus Trotz brought in — director Mitch Korn and goalie coach Piero Greco — have had a profound impact on the position.
