Atlantic Division Offseason Grades: How Each NHL Club Fared This Summer
Atlantic Division offseason grades: A team-by-team analysis of NHL summer moves, trades and signings and their impact on each club ahead of 2026-27 season.
The NHL Atlantic Division offseason grades are in, and the picture is varied across eight franchises that spent the summer reshaping rosters, addressing cap questions and betting on youth or veteran reinforcements. This review examines the key arrivals and departures that will define expectations for the 2026-27 campaign and highlights where each team appears improved, vulnerable or unresolved.
Boston acquires JJ Peterka, reshapes wing group
Boston added JJ Peterka and right-shot defender Will Borgen while losing Viktor Arvidsson and backup goaltender Joonas Korpisalo. The Peterka trade is the headline move: a young winger with upside who could benefit from playing alongside David Pastrnak and a settled top line. Borgen’s size and right-side pivoting should help stabilize a blue line that needs balance, while Korpisalo’s exit pushes Michael DiPietro into a more prominent backup role.
How this summer grades for the Bruins will hinge on immediate offensive returns from Peterka and the ability of the goaltending tandem to hold steady. If Boston extracts the 30-goal potential many envisioned for Peterka, this will look like one of the stronger Atlantic Division offseason moves.
Sabres trade Byram, lose Tuch; betting on youth and draft assets
Buffalo parted with Alex Tuch and Bowen Byram, acquiring prospects and picks including Olen Zellweger and Louis Crevier as part of a broader retooling. The Sabres clearly prioritized long-term flexibility over maintaining established veterans, and they locked up young forwards Zach Benson, Noah Ostlund and Konsta Helenius to deals that suggest internal growth is expected to fill scoring gaps. The loss of top-six scoring and a dependable blueliner is significant, however, and raises immediate questions about the club’s ability to compete next fall.
A swing-for-the-fences signing for a veteran goaltender like Connor Hellebuyck would instantly alter Buffalo’s offseason grade, but until such a move materializes the Sabres’ summer reads as cautious and forward-looking rather than immediately transformative.
Detroit’s front-office shake-up leaves roster questions
Detroit’s offseason was dominated by off-ice developments: captain Dylan Larkin requested a trade and Steve Yzerman moved upstairs, leaving the club in search of a new general manager with training camp less than two months away. Contract talks for Simon Edvinsson and the final year of Alex DeBrincat’s deal add to a sense of instability in a franchise still chasing its first postseason appearance in a decade.
Pending decisions in the front office and potential roster moves by a new GM will determine whether this offseason becomes a missed opportunity or the start of a reset. For now, Detroit’s grade reflects unresolved questions rather than clear improvement.
Florida trades for Brady Tkachuk and reinforces championship core
Florida made the marquee summer splash by acquiring Brady Tkachuk, sending the No. 9 pick and other assets to Ottawa in a deal that signaled clear championship intent. The Panthers also added Jacob Markstrom and a collection of experienced forwards and defenders to round out a roster that missed the playoffs last season due to key injuries. With Matthew Tkachuk already in town, Brady’s arrival boosts the top-nine’s physicality and scoring threat.
Goaltending will be watched closely after Sergei Bobrovsky’s departure, but the Panthers’ aggressive offseason positions them as immediate contenders again. On paper, Florida’s moves rate as one of the most consequential in the Atlantic Division.
Canadiens sign Ivan Demidov long-term while Senators reset after Tkachuk
Montreal’s busiest move was the long-term extension of Calder runner-up Ivan Demidov, a contract that locks in a promising core player on team-friendly terms. The Canadiens otherwise had a quiet summer, continuing to prioritize internal development and salary structure rather than big-name additions. That approach keeps Montreal on an upward trajectory if Demidov and the young core continue to progress.
Ottawa, by contrast, closed the chapter on Brady Tkachuk with roster pieces coming back in return, including William Eklund. The Senators’ strategy is partly about resetting cap flexibility while keeping core veterans like Claude Giroux in place. Ottawa’s offseason will be judged on whether Eklund and other incoming players can replace the production lost with Tkachuk.
Maple Leafs and Lightning make targeted upgrades to depth and defence
Toronto’s new general manager reshaped the roster with several depth signings and a major move for Darren Raddysh, while also adding veteran netminder Sergei Bobrovsky and rookie Gavin McKenna. The Leafs focused on top-end and role-player balance, pairing a veteran goaltending option with younger scoring talent and a retooled defensive group. If Raddysh becomes the top-four right-shot the club expects, Toronto’s power play and defensive transition game could see real gains.
Tampa Bay exchanged Darren Raddysh for John Carlson and added Dennis Hildeby as a potential steadier backup to Andrei Vasilevskiy. The Lightning’s moves were more incremental, addressing specific needs on the blue line and in net rather than executing a wholesale rebuild. Tampa’s offseason reads as pragmatic: keep the core intact while seeking marginal improvements that could help break recent first-round exits.
The Atlantic Division offseason grades reflect a patchwork of immediate gambles, long-term bets and front-office transitions that will only be fully judged once the puck drops in training camp. Several clubs made decisive moves to chase contention, while others restructured with an eye to controlled growth. The summer’s transactions have altered expectations across the division and set clear storylines to monitor when teams return to the ice.
