Standing at 6-foot-6 and 222 pounds, he is known for his imposing presence in the crease and exceptional athleticism. Cossa began his junior career with the Edmonton Oil Kings in the Western Hockey League (WHL), where he quickly made a name for himself. In the 2020/21 season, he led the WHL with a 1.57 goals-against average, a .941 save percentage, and four shutouts, earning the title of WHL Goaltender of the Year. After being drafted, Cossa transitioned to professional hockey, spending time with the Toledo Walleye in the ECHL and the Grand Rapids Griffins in the AHL. In the 2023/24 season, he posted a 22–9–9 record with a 2.41 GAA and a .913 SV% in 40 regular-season games with the Griffins. He also appeared in nine Calder Cup Playoff games, helping the team reach the Central Division Finals. In December 2024, Cossa made his NHL debut with the Red Wings, becoming the first goaltender in franchise history to win his debut via shootout in a relief effort. He stopped 12 of 14 shots in a 6–5 shootout victory over the Buffalo Sabres. Today, Cossa continues to develop with the Grand Rapids Griffins, providing valuable depth in goal alongside Red Wing goaltenders John Gibson and Cam Talbot.
