Monday afternoon, after being berated with questions from Leafs’ media at their introductory press conference, the 19th General Manager in the illustrious history of the Toronto Maple Leafs, John Chayka, and Senior Executive Advisor Mats Sundin joined the Real Kyper and Bourne Show to discuss their vision for the 2026-2027 Leafs. It was an interview that all Leafs fans and anyone interested in this situation should listen to, as the two men gave poised, articulate answers about their direction for the team, including their approach to Captain Auston Matthews, Winger Matthew Knies, Head Coach Craig Berube, and so much more. Fast forward to this morning, fresh off an improbable 2026 Draft Lottery win, and the return to playoff contention just became much clearer for the new regime. Although the industry views the Chayka/Sundin combination as controversial, the article below will outline reasons for optimism, especially after last night’s results.

John Chayka as General Manager

John Chayka’s path to becoming GM of the Toronto Maple Leafs is unlike almost any executive currently operating in the NHL today. As many know, Chayka became the youngest General Manager in NHL history when the Arizona Coyotes named him to the role in 2016, accelerating the NHL’s growing analytical movement and a hiring trend among hockey executives. This philosophical shift toward data-driven decision-making in hockey operations aligns directly with this site’s work, and Chayka’s background in hockey and business perfectly complements his analytical mindset. Before arriving in Arizona, Chayka had already established himself in the hockey analytics community, co-founding Stathletes, a sports data company that evolved into a multimillion-dollar enterprise supplying analytics and insights to NHL organizations and other leagues.

What makes this hire particularly fascinating for the Leafs is Chayka’s combination of analytics and organizational experience, which he now brings to the most resource-rich environment in all of hockey. During his tenure in Arizona, Chayka operated under strict financial and structural constraints, forcing him and his staff to identify inefficiencies, undervalued assets, and unconventional roster-building strategies to gain a competitive advantage. As he mentioned in several of his recent interviews, the circumstances surrounding the Arizona organization were often unstable, making the daunting task of running a hockey franchise even tougher for a 26- to 30-year-old.

That said, although the team performed poorly in the standings under Chayka, there was evidence of quality GM work during that four-year stretch. His drafting of Clayton Keller and Jakob Chychrun, and his trade for Nick Schmaltz, are among several positive moves Chayka made with Arizona. The graphic below provides additional context into Chayka’s tenure, including trade outcomes, draft results, and team trajectory during his first four-year stint as an NHL General Manager.

Although Arizona’s Average Team AB Score of 20.26 fell below the study average of 26.15, the context matters when evaluating these results. As previously mentioned, Chayka inherited a franchise operating with significantly fewer resources, structure, and ownership support than most NHL clubs, yet the trajectory illustrates a demonstrable year-to-year growth in AB performance, including a playoff appearance in the COVID bubble, beating the Nashville Predators in the qualifying round before losing to the Colorado Avalanche in the first round. Although Chayka left the club before that playoff series win, he still deserves credit for the team he built, which won a round under unforeseen circumstances.

The trade bucket data shows a similar pattern. With an AB replacement number of 1.10 from 2007 to the present, Chayka acquired more above-replacement NHL players than he traded away. He also traded more below-replacement players than he received, demonstrating his ability to recognize undervalued NHL contributors despite limited resources.

The draft outcomes are actually better than public perception suggests, based on the data. While there were players Chayka might have selected instead of those he drafted, everyone tends to be a critic with the benefit of hindsight. The fact is, the NHL draft is a crapshoot, as multiple industry executives have written about in books or discussed at length in interviews. The role of a General Manager is to leverage those picks into NHL-caliber players or flip them to accumulate more capital. 50% of Chayka’s 32 total draft picks in the AB Database reached the NHL, while 25% surpassed the 100-game threshold. These are more than respectable results given the situation.

While these insights are not perfect, they suggest that Chayka has potential managerial strength in two key GM areas: trade and draft decisions. Now, as an older, more experienced executive, it’s reasonable to think Chayka has learned from his mistakes in Arizona. With Mats Sundin’s advice and the wealth of resources and knowledge available to him at MLSE, he has an opportunity to change public perceptions of him and truly flourish under better circumstances in Toronto.

The Craig Berube Decision

When the Toronto Maple Leafs hired Craig Berube in May of 2024, following yet another early playoff exit, they believed they were bringing in an authoritative, Stanley Cup-winning coach capable of pushing the team beyond their 1-series ceiling. Although they fell just one win short of the Eastern Conference Finals in 2024-2025, Berube’s future with the team is now in question, due in large part to the relationship between the Leafs and their franchise player, Auston Matthews. This is the first of many decisions John Chayka will make this offseason, and the graph below depicts Berube’s coaching profile relative to the AB Coaching Study.

The graphic illustrates that Craig Berube, although below the Top-10 study mark of 0.78, remains considerably above the coaching study average of 0.466 with a Coaching AB Score of 0.65. Similar to the Sheldon Keefe conversation in this article Analyzing Sunny Mehta’s Offseason Checklist For the New Jersey Devils- What Changes Need to Be Made? – hockey free for all.com (HOME OF THE ADVANCED BRACTON), the data suggest Berube is a well-above-average NHL head coach. Furthermore, his Return IMP% (the percentage of players who improved under Berube across consecutive seasons) and Advantage% (the proportion of players who improved under Berube compared to their previous coach) both significantly exceed the coaching-study averages. This supports the notion that Berube typically manages effective NHL teams with a competitive structure.

The main concern arises with Berube’s Average IMP score of 0.38. Although it remains above the study’s average of -0.50, it is well below the Top-10 coaching benchmark of 1.33. This indicates that while Berube’s teams are consistently competitive and above replacement level, player development may not always meet the elite standards needed to fully realize superstar potential. For most teams, this is manageable. However, for Toronto, it is more critical due to the high expectations for Auston Matthews, especially given that, despite last night’s draft lottery win, the Leafs do not own their first-round pick in either of the next two NHL drafts. The graphic below illustrates Matthews’ AB trajectory throughout his NHL career, with emphasis on his two seasons under Craig Berube.

While injuries certainly played a role in Matthews’ decline over the last two seasons, the production drop, even when healthy, is impossible to ignore. Matthews posted a 5.66 AB Score in 2023-2024, the highest of his professional career to date, indicative of his status as one of the top 5-10 players in the sport. After Berube took over, Matthews’ output staggered to 3.86 in 2024-2025, and to the lowest mark of his career, 2.39, this past season.

This is the key issue surrounding the Maple Leafs moving forward. If John Chayka and CEO Keith Pelley are serious about the club needing a short-term fix rather than a long-term rebuild, then Auston Matthews’ return to dominance alongside William Nylander, Matthew Knies, and John Tavares should be the top priority. This doesn’t mean Berube should be dismissed, as coaching metrics suggest he’s a high-quality NHL coach capable of leading competitive teams in the right circumstances. However, Chayka, Sundin, and the rest of the Leafs management team need to spend the offseason evaluating how to place Matthews in the best possible position to rebound offensively, and a coaching change heading into 2026-2027 may be an avenue to achieve that goal.

The 2025-2026 Toronto Maple Leafs

The biggest takeaway from the 2025-2026 Leafs roster is not necessarily how strong the top of the roster is, but how fragile the rest of it is outside of the core, especially on the defensive side. The graphic below details the majority of the roster’s below-replacement status, highlighting significant roster imbalance and areas for improvement in Chayka’s first offseason.

Obviously, the Leafs’ core forward group of William Nylander (+3.37 AB), John Tavares (+2.73 AB), Matthew Knies (+2.49), and Auston Matthews (+2.39) presents an incredibly gifted group of offensive playmakers. Aside from the top four players, only Matias Maccelli and Nick Robertson surpassed the above-replacement thresholds among the forwards. Easton Cowan, in his rookie year and amid ongoing roster changes, performed nearly at replacement level, indicating positive developmental progress. However, for defensemen, only OEL and Morgan Rielly eclipsed the mark. A previous article highlighted how the Leafs, across multiple management teams, have miscast Morgan Rielly and paid the price (read here The Toronto Maple Leafs Failed Morgan Rielly- And It’s Time for Both Sides to Move On – hockey free for all.com (HOME OF THE ADVANCED BRACTON)). Without significant defensive upgrades, the Leafs’ goal of a quick rebound will be difficult to achieve.

This is where the Leafs’ situation becomes especially interesting under John Chayka. For years, previous administrations focused on maximizing star talent like the names in the previous paragraph, while attempting to patch the rest of the roster with inexpensive depth pieces. As the cap increases, and GMs have more salary ammunition to work with, Chayka has an opportunity to generate value throughout the middle and lower portions of the lineup by inserting marginal upgrades to an already established core. These are the types of roster inefficiencies Chayka spent years trying to solve in Arizona, without the star presence or resource conglomerate that he has now with the Leafs.

If Chayka is successful at finding players even slightly above the bar in the 1.3-1.8 range, the entire complexion of the Leafs’ roster changes. Factor in the immediate impact of a No.1 pick like Gavin McKenna playing top-six minutes alongside Matthews or Tavares, and these are the margins that decide playoff rounds and extend contention windows. Armed with over $22 million in cap space, according to Puckpedia.com, the Leafs are poised to add multiple significant acquisitions either through trades or free agency that can make an impact on next year’s roster.

Toronto Maple Leafs Cap Analysis

The Salary cap outlook below illustrates where John Chayka’s first major decisions become even more important, as there’s apparent flexibility to restructure the organizational depth chart quickly.

The encouraging insight from this graph for the Leafs is that the organization’s most important players are still generating positive return on investments relative to their extensive contracts. Matthew Knies’ six-year deal at 7.75 million AAV appears to be one of the better, more valuable contracts in the NHL today, projecting a valuation over $10 million. This contract was one of the finer pieces of work from the Brad Treliving era, ensuring that a homegrown power forward remains with the team up until his age-29 season.

The same concept applies to Matias Maccelli, Nicholas Robertson, and Easton Cowan. If the Leafs are serious about a quick retool rather than a long-term rebuild, they have three capable forwards already in-house that they should surround their core stars with. Maccelli and Robertson both generated scores higher than replacement, and Cowan nearly reached replacement level as a rookie surrounded by uncertainty. Young, cost-controlled players like these who outperform their contracts are perfect examples of the depth that moves the needle in the playoffs, and are critical for resource allocation towards the rest of the roster.

Defense should be an extreme priority for the club, as previously mentioned in other sections, because several players are occupying meaningful cap space while performing below replacement level. Luckily, there are several quality defensemen available in free agency that would be tremendous additions to a Leafs team looking to rebound, such as Anaheim’s Jacob Trouba (+1.45 AB) and John Carlson (+2.67 AB), Tampa Bay’s Darren Raddysh (+3.35 AB), and Vegas’ Rasmus Andersson (+2.02 AB). With their existing $22 million in cap space, along with the prospect of adding more through trades, it’s reasonable to suggest that the Leafs could target two of those names to improve the group, as if they elect to select McKenna at No. 1, their longer-term defense problems remain intact.  It’ll surely be interesting to evaluate Chayka’s decision-making in this area as the offseason progresses, as there’s still a massive opportunity to make the upgrades needed to catapult the Leafs back into contention in the Atlantic Division.

Matthew Knies- The Top-6 Forward the Leafs Should Absolutely Not Part With

If there’s one player or asset the Maple Leafs should view as untouchable during this pivotal offseason, it is Matthew Knies. Despite the Leafs’ urgent need for defensive upgrades and likely involvement in various trade rumors about available defensemen, they cannot afford to trade away one of their few young, high-performing power forwards on a great contract. The graphic below highlights Knies’ current trajectory, contract outlook, and statistical comparables entering 2026-2027.

The data above reinforce just how valuable Knies has already become for the Leafs organization. His 66-point season with a 2.49 AB Score at age 23 puts him in rare company. Even more notably, his six-year contract with a modest $7.75 million AAV in a league with rising salaries seems to be a bargain, as the model estimates his performance warrants a $2.25 million salary increase.

What makes Knies especially important for the current iteration of the Leafs, however, extends beyond offensive production. For years, the underlying criticism of the Core 4 era was the lack of physical edge and interior toughness with the club as a whole. At 6’3, 230 lbs., Knies brings that blend of size, puck protection, and physicality that Toronto has lacked around its core stars for much of the last decade. Players with his combination of age, production, ability, and physical presence are extremely difficult to acquire, which is exactly why the Leafs shouldn’t entertain moving him under the false pretense of an organizational surplus at his position.

John Chayka and his management team are responsible for creatively improving the defense corps and supporting the roster around the core, including Matthew Knies. Trading Knies for defensive help just creates another hole in the top-6, especially given the rarity of Knies’ attributes in the NHL today.

Additionally, if Gavin McKenna is indeed the first overall pick, Knies’ importance arguably increases even more. In addition to the statistical production already mentioned, there’s substantial value in having a physically imposing winger within the top-six capable of protecting a younger, more skilled player like McKenna as he transitions from the Big-10 to the NHL. Knies’ presence alone changes how opponents physically engage with the Leafs’ skilled players. Although these elements don’t appear on a score sheet, they unquestionably matter during the regular season and are amplified for the playoffs.

The Leafs have spent years searching for a player like the one Matthew Knies is becoming. Trading him now, on a great contract heading into his prime, would contradict nearly every lesson Toronto should have learned throughout the Matthews era. This is a rare combination of size, skill, and toughness that a championship team absolutely must have, and he should be viewed as a foundational piece of this team for the foreseeable future.

Gavin McKenna- An Incredible Possibility

Last night’s lottery drawing may have altered the trajectory of the Toronto Maple Leafs’ organization more than any single event other than winning the Auston Matthews lottery 10 years ago. The Leafs may have just stumbled upon their Mitch Marner replacement alongside Matthews for 2026-2027, as Marner’s point production was definitely missed in 2025-2026. The graphic below highlights the potential first overall pick, Gavin McKenna’s offensive profile, a projected AB Score for 2025-2026 with Penn State University, and historical production comparables entering the NHL.

McKenna’s projected AB Score of 2.38 stands dramatically above the NHL’s replacement-level AB benchmark of 1.17. While collegiate and junior production are obviously not treated as a direct, one-to-one NHL translation, a projection exceeding that replacement level by such a margin indicates a player whose offensive profile already aligns with immediate NHL effectiveness and elite scoring upside.

The projection becomes even more interesting when viewed alongside McKenna’s actual production history. Before attending Penn State, McKenna dominated the WHL with the Medicine Hat Tigers, recording 129 points in 56 games during the 2024-2025 season after a 97-point output the year prior. He then transitioned to the college level fairly seamlessly, recording 51 points in 35 games as a freshman, in addition to an exceptional 2026 World Junior Championship with Team Canada, where he had 14 points in 7 games. Across junior, college, and international competition, McKenna has shone and remains dominant relative to his peers, especially as a playmaker.

When determining comparables using data from NCAA public databases or Penn State post-game box scores, the AB projection reflects 29 variables, 29 of which are certain and 10 are estimated, which together generate an AB Score. The comparables section was generated through an analysis of pre-NHL production profiles, historical player data from HockeyDB.com, and the extensive AB database collection. The system identified winger prospects whose offensive trajectories prior to the NHL closely resembled McKenna’s, and then cross-referenced them against the AB database, using first-year AB data to generate a meaningful match.

The results should be extremely encouraging for the Leafs, as McKenna’s offensive and AB comparables include players such as Jason Robertson, Clayton Keller, and Johnny Gaudreau, all of whom became high-end offensive players shortly after entering the league full-time. From Toronto’s perspective, hearing McKenna himself say he models his game after Nikita Kucherov and uses elements of his creativity, vision, and offensive output to help return Auston Matthews to MVP form is certainly an enticing option.

McKenna’s possible addition changes the organizational discourse surrounding the Leafs in previous years. For the first time in the Matthews era, the Leafs could finally have an elite offensive prospect on an entry-level contract to develop around a core of superstars while simultaneously extending the franchise’s short-term window as an entry-level contract player. We saw the impact Matthew Schaefer made on the New York Islanders in 2025-2026, as written in the article here, Mathieu Darche Has the Islanders Headed in the Right Direction — Why They Can Make the Playoffs Next Season – hockey free for all.com (HOME OF THE ADVANCED BRACTON). A full 2026 Draft write-up will be coming soon. Alongside Matthews, it’s reasonable to guess that McKenna could be in Calder conversations next season, especially if the Leafs return to being the perennial playoff contender they were for the past decade.

Conclusion

For John Chayka, Mats Sundin, and the rest of the Maple Leafs’ front office, the lottery results last night changed everything. They already inherited a team of veteran stars, solid cap space, and a younger group of above-AB-replacement forwards capable of supporting the upper group, but now they potentially have a generational winger at a league-minimum cap hit for the next three years to accelerate the retool. Whether or not the Leafs return to playoff contention depends heavily on Chayka’s ability to maximize value, use data-driven insights to aid in smart managerial decision-making, and creatively improve the roster without creating additional holes. If he’s successful, then the Leafs’ Stanley Cup window is right back open, perhaps even longer than many believed possible only a few days ago.
