Before the 2025-26 season, the Boston Bruins acquired German-born forward JJ Peterka from the Utah Mammoth, adding an established top-six scoring option to their forward group.

The price was substantial: Boston sent the 23rd overall pick in 2026 and the Florida Panthers’ first-round selection in 2028. Peterka began his NHL career with the Buffalo Sabres in 2022-23, recording 32 points in 77 games. That was only an initial sample, however, and there was still considerable room for his game to grow.
Peterka’s Breakout Season in Buffalo (2024-25)
As a Sabre in 2024-25, Peterka produced 68 points, including 27 goals and 41 assists, in 77 games. He displayed his best results alongside players such as Tage Thompson and Alex Tuch, with the three forming a line that played 23 games together.
That unit was one of Buffalo’s strongest, posting a 55.90 Corsi-for percentage and a 56.28 expected-goals-for percentage. According to Natural Stat Trick, it generated 11 goals for and allowed eight while on the ice.
Those results suggest that Peterka is most likely to thrive in Boston when paired with playmakers and finishers capable of creating scoring chances for him.
Peterka’s First Season With Utah (2025-26)
Buffalo traded Peterka to the Mammoth for Josh Doan and Michael Kesselring before the 2025-26 season. His production declined in his new surroundings, as he registered 47 points—25 goals and 22 assists—in 82 games.
In 21 games with Logan Cooley at center and Dylan Guenther on the right wing, the trio was less effective at maintaining puck possession, recording a 50.93 CF% and a lower 46.92 xGF%.
Peterka finished three goals short of the 28-goal career high he set in 2023-24. His first and only season as a Mammoth forward was not a failure, but Boston provides an opportunity for him to continue developing.
Finding the Right Role in Boston
Selected 34th overall by Buffalo in the 2020 NHL Draft, Peterka gives the Bruins a legitimate top-six scoring threat.
Across 320 NHL games split between the Sabres and Mammoth, he has accumulated 197 points—92 goals and 105 assists—including 35 power-play points, comprising 14 goals and 21 assists.
“He’s competitive,” Bonvie said of Peterka. “He’s shutting down and closing gaps. He’s got some length. He’s got some bite on the back end, which we feel like we can use. It’s going to make us a hard out in terms of playing against really good teams and making it hard on their best players. We felt there was a little bit of a need and a spot there for him. He’s going to have to come in and continue to elevate his game. But we feel he can do that” (from ‘Bruins assistant GM Dennis Bonvie on JJ Peterka trade, upside-focused pro scouting approach‘ The Athletic, Fluto Shinzawa, 9/1/26).
Unlike previous attempts to force prospects into unsuitable roles, the Bruins appear to have identified a genuine two-way forward who can contribute in all three zones.
Pairing Peterka With Zacha or Minten
Peterka should benefit from head coach Marco Sturm’s emphasis on developing young players. Sturm enters his sixth season as an NHL head coach and inherits a forward group that urgently needs dependable depth.
Daily Faceoff has projected Peterka onto the first line and the second power-play unit. Those assignments could become reality depending on his training camp performance, as he will compete with Casey Mittelstadt and James Hagens for a top-six position.
With a $7.7 million cap hit, Boston will expect Peterka to deliver top-line minutes, provide consistent two-way play and add another 20-goal season to his career totals in 2026-27.
