Sebastian Cossa's story
Raised in Fort McMurray after being born in Hamilton, he learned much of the game in Saskatchewan before returning to Alberta for organized youth hockey. He played U15 for the Fort McMurray Oil Barons and later for the Fort Saskatchewan Rangers at U15 and U18 levels, where he helped the club to a U15 championship. Edmonton selected him in the second round, 36th overall, of the 2017 WHL bantam draft and he made his Oil Kings debut in October 2017, recording an early shutout performance.
Cossa's junior résumé includes standout statistical seasons and monthly honours. As a rookie he posted a high save percentage and earned WHL Goaltender of the Month recognition; in 2020–21 he led the WHL in goals-against average, save percentage and shutouts, and set a franchise mark for consecutive wins to start a season. Those results put him among top goaltending prospects and Detroit took him with the 15th overall pick in the 2021 NHL Entry Draft. He signed a three-year entry-level contract in August 2021 and continued to collect WHL monthly awards into the autumn.
The professional phase of his career began with an AHL debut for the Grand Rapids Griffins on October 19, 2022. He was reassigned to the Toledo Walleye of the ECHL the following day and recorded his first pro shutout on January 21, 2023 while helping Toledo to a deep playoff run. Back in Grand Rapids, he posted a strong 2023–24 AHL campaign, appeared in the 2024 Calder Cup playoffs and helped the Griffins reach the Central Division finals.
Détroit recalled him on an emergency basis on December 2, 2024, and he made his NHL debut on December 9, entering in relief of Ville Husso; he stopped 12 of 14 shots in a 6–5 shootout victory over Buffalo, becoming the 11th goaltender in Red Wings history to record a win in his NHL debut. Across multiple AHL seasons he amassed significant playing time, was selected to AHL All-Star Games in 2025 and 2026, and compiled strong overall numbers before being traded on June 26, 2026 to the Utah Mammoth and signing a two-year contract extension at the end of that month.
In plain terms, he profiles as a puck-stopping goaltender whose junior success was built on elite save percentages and the ability to string together wins; his development path relied on heavy workloads in junior and AHL minutes before breaking through briefly at the NHL level.
