There is a particular stillness that great defensemen carry with them, a sense that the chaos of the game swirls around them without ever quite touching them. Matthew Schaefer, at nineteen, seems to possess that stillness already. His coach calls him unflappable, and the word fits—not because nothing moves around him, but because he moves through it all with a composure that belies his age. A year after sweeping every rookie vote for the Calder Trophy, the Hamilton native is showing that the sophomore slump is not a law of nature.
The numbers tell part of the story. Through twelve games, Schaefer leads the New York Islanders in ice time at 26:43 per night, and he sits second on the team with eleven points . On Tuesday against Nashville, he became the first skater on record—dating back to 2009-10, when real-time tracking began—to play all five minutes of overtime, finishing with a career-high 32:16 of action . These are not the statistics of a player easing into his second season. They are the statistics of a player his coach cannot bear to take off the ice.
Pete DeBoer, who joined the Islanders late last season after a long career behind NHL benches, first encountered Schaefer while scouting for Canada's Olympic team. He watched the video and saw a good player. Then he saw him in person. "He's even better live and in-person than he is on tape," DeBoer said. "A real difference-making player. There are very few of them in the world, and he's one" . The phrase "unflappable guy" came from DeBoer too, offered with the casual certainty of a coach who has seen a great many players and knows when he is looking at something rare.
What makes Schaefer's start remarkable is not just the production but the responsibility. He is an alternate captain now, a letter stitched to his jersey in just his second professional season. "People gravitate toward him," DeBoer said. "He's got great leadership. Mature beyond his years for a young guy. He's already got a voice in our room" . Captain Bo Horvat pointed to a different quality: the 200-foot game, the ability to be first on the forecheck and first back, the kind of effort that does not always show up in a box score but shapes a team's identity .
The rookie season that preceded this one was historic. Schaefer was the first unanimous Calder winner since Teemu Selanne in 1992-93, sweeping all 198 ballots after posting 59 points in 82 games. He became the first defenseman in more than nine decades to lead all rookies in goals, with 23, and he set records for points by an 18-year-old blueliner . The Islanders selected him first overall in 2025, and he has done nothing since to suggest that choice was anything but correct.
He nearly made Canada's Olympic roster for Milan Cortina, a decision DeBoer said went down to the final day. In hindsight, with Josh Morrissey injured early, DeBoer acknowledged that Schaefer "probably could have helped us" . It is a small regret, the kind that accompanies almost every roster decision, but it speaks to how quickly Schaefer has moved from prospect to player that coaches wish they had.
Schaefer himself speaks with the same evenness that defines his game. "I have high expectations," he said. "I want to be the best version of myself on and off the ice. There's gonna be days you don't feel like you're at your best. There's gonna be days where you feel like you're awesome" . The acknowledgment of both—the bad days and the good—is the mark of a player who understands that a season is long and a career is longer.
For now, the Islanders are 6-4-2, and Schaefer is playing more than any skater on the team. The sophomore slump has not arrived, and there is no sign it is on its way. What remains is the quiet pleasure of watching a young player grow into exactly what he was expected to become, one shift at a time.
