The New York Islanders fired head coach Patrick Roy in early April with four games left in the regular season, naming veteran bench boss Peter DeBoer as his replacement. The move did not salvage the season — the Islanders missed the playoffs for a second straight year — but the campaign at UBS Arena was defined less by the coaching change than by the arrival of an 18-year-old defenseman who quickly became one of the most exciting rookies in hockey.

The firing

First-year general manager Mathieu Darche made the abrupt call after the Islanders lost a season-high four games in a row and seven of 10 since March 18, collapsing out of a playoff race they had been clinging to. Roy, the Hall of Fame goaltender turned coach, had compiled a 97-78-22 record over three seasons since taking over for Lane Lambert. Darche replaced him with DeBoer, signing the new coach through the 2028-29 season — a sign the organization wanted a long-term answer behind the bench rather than an interim fix.

Matthew Schaefer’s debut season

The bright spot was unmistakable. Matthew Schaefer, whom the Islanders selected first overall in the 2025 NHL Draft after winning the lottery, was a revelation. The 18-year-old defenseman finished his rookie year with 23 goals, tying Brian Leetch’s single-season record for goals by a rookie defenseman, and entered the offseason as the presumptive Calder Trophy front-runner.

Schaefer’s first NHL goal became one of the season’s signature UBS Arena moments — a diving, Superman-style poke of a loose puck into the net in the second game of the year, on Oct. 11, that sent the crowd into a chant of his name as officials reviewed the play. He was a steadying, dynamic presence on the back end all year for a team in transition.

A season of highs and a hard finish

There were nights to remember at Belmont Park. The Islanders thumped the New Jersey Devils 9-0 at home, with Anthony Duclair recording a hat trick and captain Mathew Barzal among the scorers. But the team could not sustain it. The regular-season finale, fittingly, came at UBS Arena against the Carolina Hurricanes — a 2-1 loss that closed the book on a 2025-26 season that went 1-5 in April and ended without a postseason berth.

Why it matters

For the Islanders, the season was a study in contrasts: a fired coach and a second straight missed playoffs against the emergence of a franchise cornerstone in Schaefer. With a new general manager in Darche, a new coach in DeBoer locked in through 2029 and a generational young defenseman, the organization is betting that its rebuild has a clear center even after a disappointing finish. UBS Arena at Belmont, on the Queens-Nassau border, will be the stage for whether that bet pays off.
