Islanders' Schaefer wins Calder Trophy

New York Islanders defenseman Matthew Schaefer has unanimously won the Calder Trophy as the NHL's rookie of the year.

Schaefer is the first player to receive every first-place vote for the award since 1993.

The 18-year-old led all rookies with 23 goals and 59 points, solidifying his status as a generational talent.

In an emotional moment, Schaefer dedicated the award to his late mother, who passed away during his breakout season.
