Weegar Traded to Utah Mammoth, Recasting Flames’ Defense with Prospects and Picks
The Calgary Flames moved defenseman MacKenzie Weegar to the Utah Mammoth in exchange for defenseman Olli Maatta, forward prospect Jonathan Castagna, and three 2026 second-round picks (owned by Utah, the Rangers and the Senators). Weegar waived his no-trade clause and is signed through 2030-31 with a $6.25M cap hit. He’s having a down year (21 points, -35 in 60 games) after a 47-point season in 2023-24, though his prior underlying metrics had been strong. The Mammoth aim to bolster their defense with a mix of left- and right-handed players; Castagna is a 6'2" center who has 14 goals and 18 assists in 29 games at Cornell this season, and Maatta’s role has diminished in Utah, with the 31-year-old under contract for two more seasons after 2025-26 at a $3.5M cap hit.
