On the first night of the Draft, Utah made a move to add goaltender Sebastian Cossa from the Detroit Red Wings, and the Mammoth are getting a netminder who has already logged plenty of miles on the road to the NHL.
Cossa’s story starts in Hamilton, Ontario, where he was born before growing up in Fort McMurray, Alberta. He is the son of Gianni and Sandra, has an older brother named Nicholas, and married his wife, Emerson, last summer.
His hockey path began in Alberta, first with the Fort McMurray Oil Barons’ U15 AA team and then with the Fort Saskatchewan Rangers at the U15 AAA and U18 AAA levels. From there, he moved on to the Edmonton Oil Kings in the WHL, where he spent three seasons beginning in 2019-20.
Cossa’s second year with Edmonton was his breakout at that level. He posted the WHL’s best goals-against average at 1.57 and the league’s best save percentage at .941. After the 2020-21 season, Detroit took him 15th overall in the draft.
He kept building from there. In his third season with the Oil Kings, Cossa helped Edmonton win the 2022 WHL Championship in his first playoff appearance with the club, alongside Mammoth forward Dylan Guenther. Over his WHL career, Cossa played 98 games and finished with a 2.12 goals-against average, a .921 save percentage, 14 shutouts and a 71-16-7 record.
After the 2021-22 season, he turned pro and entered the Red Wings organization. His first professional year was split between the Toledo Walleye of the ECHL, where he played 46 games, and the Grand Rapids Griffins of the AHL, where he appeared in three games. By the 2023-24 campaign, he was with Grand Rapids full time.
That’s where most of his pro work has come. Over the last four seasons, Cossa has played 123 games for the Griffins and put up a 70-33-19 record with a 2.46 goals-against average, a .911 save percentage and eight shutouts. In three playoff appearances with Grand Rapids, he has played 11 games and gone 5-6-0 with a 3.04 goals-against average and a .893 save percentage.
Cossa also got a taste of the NHL with Detroit on Dec. 9, 2024.
He stopped 12 of 14 shots and picked up his first NHL win. After all that AHL experience, he is expected to make the jump to the NHL as Karel Vejmelka’s backup.
Internationally, Cossa helped Canada win gold at the 2022 IIHL World Junior Championship. He appeared in one game at the tournament, won that start, and finished with a 2.00 goals-against average and a .917 save percentage.
He also represented Canada White at the 2018 World Under-17 Hockey Challenge, where he played two games and posted a 3.03 goals-against average with a .895 save percentage.

Mammoth Could Be Lining Up One More Massive Trade Swing
Utah has already spent the offseason making itself harder to ignore, adding Vincent Trocheck and Anders Lee as it keeps reshaping the roster around more proven help. Even with those moves in place, the front office does not appear finished, and the idea of another major swing has started to follow the club as it looks for more offense and a higher ceiling heading into the season.
The challenge, of course, is that any pursuit of a top-end scorer is going to come with a real price tag, and that is where the conversation gets interesting for Utah. A move of that size would likely require parting with meaningful young talent and prospects, which is the kind of decision that can define a teams next several years, especially when the target is a player other clubs are also believed to be chasing.
