Sebastian Cossa has quickly become a focal point in Salt Lake City following his recent trade to the Utah Mammoth. After joining the team just days prior to a brief vacation, the goaltender made time to explore the organization’s facilities and connect with the media for the first time, expressing a straightforward objective for the upcoming season.
“My primary goal is to come in and play well enough to help us win as many games as possible,” Cossa stated.
While his ambition might seem bold for a goaltender with only one NHL appearance to date, significant confidence has permeated through the Mammoth organization. Cossa’s track record in the American Hockey League (AHL) has exceeded expectations, earning him trust not only from himself but also from team leadership.
A Match That Was Needed
Drafted 15th overall by the Detroit Red Wings five years ago, Cossa has primarily developed within the organization’s AHL affiliate, the Grand Rapids Griffins. His minor league tenure included a stint in the ECHL during his rookie season and an NHL debut in 2024. Over three full AHL campaigns, Cossa consistently posted save percentages exceeding .910, amassing 69 victories, earning two All-Star selections, and claiming the Harry “Hap” Holmes Memorial Award—the league’s top goaltender honor—in his most recent season.
“Those AHL seasons and the year in the ECHL were crucial for gaining experience, and I’m focused on continuing to improve,” Cossa reflected.

Despite his potential, the Red Wings’ goalie rotation—bolstered by veterans like Ville Husso, James Reimer, and Petr Mrazek—left little room for advancement. With younger prospects Trey Augustine and Michal Postava also vying for opportunities, a change of scenery became necessary for Cossa’s development.
The Mammoth, seeking stability at backup goaltender following Connor Ingram’s departure, saw Cossa as a promising fit. While former backups like Vítek Vaněček, Matt Villalta, and Jaxson Stauber struggled, GM Bill Armstrong placed unwavering faith in Cossa’s potential. “His AHL performance highlights his readiness, and his age aligns perfectly with the team’s trajectory,” Armstrong said. “He has a real chance to become a cornerstone.”
Confidence Can Go a Long Way
The trade itself underscored the Mammoth’s commitment: a first-round pick acquisition paired with an immediate two-year contract extension signaled strong belief in Cossa’s capabilities. “Being brought in with such trust and a contract extension is motivating. I know there’s work to do, but I’m ready for this challenge,” Cossa said.
Cossa’s familiarity with Mammoth stars like Dylan Guenther and Logan Cooley, forged during their shared WHL championship run with the Edmonton Oil Kings, positions him well. Head coach André Tourigny’s prior work with Cossa at the World Juniors further strengthens their rapport. The goalie’s hobbies—fishing, hiking, and golfing—align with team culture, and he looks forward to bringing his dog to Salt Lake City.
At 23, Cossa could serve as Karel Vejmelka’s backup and potentially evolve into a long-term starter alongside Michael Hrabal, the organization’s future netminding asset. “We’re giving him the chance to take that next step, and who knows what he might achieve?” Armstrong noted.

With the Mammoth poised for continued success, Cossa understands the heightened expectations of his rookie season. “I’ll work every day to prove why I was acquired and contribute to winning,” he said. “I’m committed to being a reliable teammate and helping this team succeed.”
