The Boston Bruins acquired forward JJ Peterka from the Utah Mammoth on Friday in a trade involving two future first-round draft picks. Utah received the No. 23 pick in the 2026 NHL Draft and a conditional first-round selection for 2028, a pick originally held by the Florida Panthers. Utah subsequently traded the 2026 selection to the Detroit Red Wings to acquire goaltender Sebastian Cossa.
Why did the Bruins target JJ Peterka?
Boston general manager Don Sweeney stated the team pursued Peterka to increase offensive depth and team speed. According to Sweeney, the 24-year-old forward provides an “elite shot” and versatility to play both wings. The Bruins intend to use Peterka to bolster their power-play units, noting that his production at 5-on-5 remains strong despite a dip in power-play ice time last season.

How does the trade impact Utah’s roster strategy?
Utah general manager Bill Armstrong described the move as a necessary step to create room for younger players. By parting with Peterka, Utah secured two first-round assets, one of which directly facilitated the acquisition of goaltender Sebastian Cossa. Armstrong expressed confidence that Cossa, who posted a 2.33 goals-against average in the AHL this season, is prepared to take that next step.
Comparison: Asset Management
| Team | Acquisition | Cost |
|---|---|---|
| Boston Bruins | JJ Peterka | 2026 1st Round Pick, 2028 1st Round Pick |
| Utah Mammoth | Sebastian Cossa | 2026 1st Round Pick |
What are the long-term implications for both franchises?
The trade signals a shift in priorities for both clubs following first-round playoff exits. For the Bruins, the addition of Peterka—who has four years remaining on a $38.5 million contract—is an attempt to add speed to their lineup. For Utah, the move prioritizes long-term stability in the crease. According to Armstrong, the team identified Cossa as a goaltender who has a chance to be a goaltender of the future.
