The Toronto Maple Leafs attempted to acquire JJ Peterka from division rival Buffalo Sabres earlier this offseason. The trade package offered by Toronto involved defenseman Brandon Carlo, but Buffalo ultimately decided to send Peterka to the Utah Mammoth for a deal they valued more highly.
JJ Peterka, who was a pending restricted free agent (RFA) and had requested a trade, was sought after by several teams. Before Buffalo completed the trade with Utah, NHL insider Frank Seravalli disclosed that the Maple Leafs had pursued Peterka by proposing a package including Brandon Carlo, a right-shot defenseman the Sabres were keen to acquire.
Buffalo Sabres Preferred Utah’s Trade Offer Over Toronto’s Package
The Sabres chose to trade Peterka outside their conference, obtaining two promising NHL players in return. Central to the agreement was Michael Kesselring, a 6-foot-5 right-shot defenseman whom Buffalo general manager Kevyn Adams identified as a key target during the offseason.
One of our priorities as we work through this offseason is making our team more competitive and tougher to play against,
Adams explained.
The additions of Michael and Josh will help us tremendously in both of those categories and I am excited to see them in a Sabres uniform soon.
Michael fits the mold of the right-handed defensemen we have been looking for, and we are thrilled he brings both size and compete,
Adams added.
We believe he will help add balance to our blue line while elevating the rest of the D corps. Josh is a player that has shown the ability to win at multiple levels and brings great leadership pedigree to our organization. He’s a strong two-way player who we believe will be able to provide versatility to our group.

Kesselring, who will be an RFA after completing the final year of his two-year, $2.8 million contract, delivered 7 goals and 22 assists for 29 points throughout 82 games last season. Alongside Kesselring, forward Josh Doan also came to Buffalo, adding depth and leadership potential.
Details on the Leafs’ Proposed Trade and Brandon Carlo’s Role
Brandon Carlo, the centerpiece of Toronto’s offer, was acquired by the Maple Leafs from the Boston Bruins at the trade deadline. He has two years remaining on his six-year, $24.6 million contract. However, Boston retained a portion of his salary, which reduced Carlo’s cap hit to $3.485 million per year with Toronto.
Last season, Carlo played in 83 games between Boston and Toronto, contributing modestly on offense with 1 goal and 11 assists for 12 points. Despite his defensive presence, Buffalo apparently preferred the package from Utah, which focused on youth and size additions.
Meanwhile, Peterka committed to Utah by signing a five-year, $38.5 million contract after the trade. He posted impressive numbers last year with 27 goals and 41 assists, totaling 68 points in 77 games.
Buffalo Sabres’ Strategy Behind Trading Peterka
Moving Peterka allowed the Sabres to address specific roster needs, namely bolstering their defense with a right-shot player like Kesselring. GM Kevyn Adams emphasized that their offseason efforts aim to build a more competitive team capable of challenging opponents physically.
The Sabres’ choice indicates a long-term plan to strengthen their blue line while injecting fresh talent and leadership through the additions of Kesselring and Doan.
Toronto Maple Leafs’ Search for a Top-Six Forward Continues
After losing star forward Mitch Marner this offseason, the Maple Leafs remain intent on adding another top-six forward to fill his absence. Although Toronto acquired Mattias Maccelli from Utah, GM Brad Treliving openly acknowledged that the team has yet to replace the offensive production Marner provided.
Mitch was a top-six forward, and we haven’t replaced that hole,
Treliving said on July 1.
That’s really where our focus is.
With just under $5 million in cap space available, Toronto is expected to remain active in seeking a forward who can contribute at a high level and complement their existing offensive core.
Implications for Both Teams Moving Forward
The Sabres secured a package that fits their current needs and development timeline, adding size and versatility on defense and a promising young forward in Doan. This trade signals Buffalo’s commitment to building a tougher, more balanced roster for future seasons.
For Toronto, missing out on Peterka means they will need to explore other options to enhance their forward group, especially in light of Marner’s departure. The Maple Leafs’ ongoing pursuit of a top-six forward remains pivotal to their aspirations in the upcoming NHL season.
