The New York Islanders enjoyed a remarkable 2018-19 season, defying preseason expectations to finish second in the Metropolitan Division with 103 points. Under the leadership of new head coach Barry Trotz and general manager Lou Lamoriello, the team transformed into a defensive powerhouse, allowing a league-low 191 goals and earning goaltenders Robin Lehner and Thomas Greiss the William M. Jennings Trophy. The season was highlighted by a resilient team culture and a thrilling first-round playoff sweep of the Pittsburgh Penguins, marking the franchise's first postseason sweep since 1983 and re-establishing the Islanders as a elite contender in the NHL.
