Islanders' Matthew Schaefer Makes NHL History With Unanimous Calder Trophy Win
The New York Islanders entered the 2025-26 season with a lot of unknowns.
After missing the playoffs for the first time since 2022 during their first full season under head coach Patrick Roy, one of the greatest goaltenders in NHL history, the Islanders suddenly found themselves relying on a rookie defenseman to restore relevance to a drifting franchise.
New York improved from 35-35-12 to 43-34-5, but it still was not enough to save Roy, who was fired in April amid another late-season collapse.
The organization spent much of the season caught between rebuilding for the future and squeezing one more run out of an aging core.
Yet, even amid another missed postseason, one development changed the entire outlook of the franchise: Matthew Schaefer, the No. 1 pick in the 2025 NHL Draft.
On Wednesday, Schaefer officially captured the Calder Memorial Trophy as the NHL's Rookie of the Year, and he did it in a way the league has literally never seen before.
The 18-year-old became the first defenseman ever to win the award unanimously and the youngest player in NHL history to win the Calder, edging Nathan MacKinnon by one day.
He also became just the second unanimous Calder winner at any position since Teemu Selanne in 1992-93.

Schaefer, a Hamilton, Ontario native, starred for the OHL's Erie Otters before becoming the Islanders’ first overall pick in 2025.
He was the third Otters player in history to get selected No. 1 overall in the NHL draft, alongside stars Ryan O’Reilly and Connor McDavid.
He made his NHL debut on October 9 in the Islanders' season opener against the Pittsburgh Penguins, recording his first career point with a first-period assist on a goal by Jonathan Drouin.
Two days later, against the Washington Capitals, Schaefer scored his first NHL goal, becoming the second-youngest defenseman in league history to net his first career goal at 18 years and 36 days old.
By the end of the season, he hadn’t just emerged as one of the top young defenseman in hockey, but as a bona fide superstar.

Schaefer finished with 23 goals and 59 points in all 82 games, tying Brian Leetch for the most goals ever by a rookie defenseman while surpassing the legendary Phil Housley for the highest point total ever recorded by an 18-year-old blueliner.
He also became the first defenseman in more than 90 years to lead rookies outright or tied in goals.
And the workload was arguably even more impressive than the production.
Schaefer logged more than 2,023 minutes of ice time, over 500 more than any other rookie in the league, and averaged nearly 25 minutes per game at age 18 while routinely facing opposing top lines.
The Islanders still missed the playoffs, but Schaefer has fundamentally changed the trajectory of the organization.
A team that looked directionless last summer now has a legitimate foundation piece capable of attracting free agents and accelerating a rebuild.
