The Mammoth didn't just add a promising young goaltender—they may have secured the cornerstone of their future in net.

The Utah Mammoth may have just landed the goaltender they've been searching for.

In a move that could shape the franchise for years to come, Utah acquired one of hockey's top young netminders on Friday, landing Sebastian Cossa from the Detroit Red Wings in exchange for the 23rd overall pick in the 2026 NHL Draft.

The trade marks a significant investment in the future. Once viewed as a cornerstone of Detroit's rebuild after being selected 15th overall in 2021, Cossa arrives in Utah with the pedigree, development, and upside to eventually become a long-term No. 1 goaltender.

Detroit immediately used the 23rd overall selection to draft Kamloops Blazers winger JP Hurlbert, signaling its confidence in another promising goaltending prospect already within the organization.

Cossa has spent the past several seasons developing with the Grand Rapids Griffins, where he continued to justify the excitement surrounding him. The 23-year-old put together an outstanding 2025-26 campaign, posting a 26-8-4 record with a 2.33 goals-against average and a .915 save percentage while establishing himself as one of the American Hockey League's most promising young goaltenders.

His departure wasn't a reflection of disappointment as much as it was a product of Detroit's organizational depth.

The Red Wings also have Trey Augustine waiting in the wings. A second-round pick in 2023, Augustine blossomed into one of college hockey's elite goaltenders during three seasons at Michigan State, finishing his final collegiate campaign with a 24-9-1 record, a 2.11 goals-against average, and a .929 save percentage before making his professional debut with Grand Rapids late in the season.

With two highly regarded young goaltenders on the same development track, Detroit ultimately chose to capitalize on Cossa's value.

For Utah, the timing couldn't be better.

Karel Vejmelka carried one of the NHL's heaviest workloads last season, appearing in more games than any other goaltender while helping the Mammoth reach the Stanley Cup Playoffs in just the franchise's second season since relocating from Arizona. He finished with a 38-20-3 record, a 2.75 goals-against average, and a .897 save percentage.

Adding Cossa gives Utah another legitimate option in goal while strengthening the organization's long-term outlook at one of hockey's most important positions. Whether he begins the season in the AHL or earns NHL opportunities sooner than expected, the Mammoth have added a goaltender many believe still possesses franchise-caliber potential.

For a team intent on building sustainable success, Friday's move may ultimately be remembered as far more than a draft-day trade. It could be the day Utah found its goalie of the future.
