Wear history on your back with this 2026 Calder Memorial Trophy Winner Matthew Schaefer T-Shirt from Fanatics. At only 18 years and 195 days old, Schaefer became the youngest defenceman in NHL history to reach 50 career points, just one part of a record-breaking debut season that left the entire league speechless. He swept all 198 first-place votes to become the first unanimous Calder Trophy winner in over 30 years, a distinction not seen since Teemu Selanne in 1993. This commemorative Matthew Schaefer shirt is the best way to celebrate the New York Islanders legend-in-the-making.
