Henry Thrun and William Villeneuve: Toronto Maple Leafs’ Defensive Depth and NHL Call-Up Prospects

The Toronto Maple Leafs find themselves in a precarious position as defensive struggles continue to plague the organization. With veteran blueliners underperforming and the team hemorrhaging goals at an alarming rate, attention has shifted to the Toronto Marlies, where two defensemen are making compelling cases for NHL opportunities. Henry Thrun and William Villeneuve have emerged as potential solutions to Toronto’s blue line woes, combining offensive production with the mobility and puck-moving skills the big club desperately needs.

The Maple Leafs currently allow a league-worst 3.83 goals against per game and have surrendered the most goals at five-on-five with 50 through their first 17 games. This defensive collapse represents a dramatic departure from last season’s identity, when Toronto prided itself on limiting quality chances. The mounting pressure has forced management and coaching staff to consider internal solutions, and both Thrun and Villeneuve have positioned themselves as viable candidates to inject new life into a struggling defensive corps.

Why the Toronto Maple Leafs defensive depth needs Henry Thrun and William Villeneuve call-ups now

The case for promoting Thrun and Villeneuve becomes increasingly compelling when examining the performance of current roster players. Simon Benoit and Philippe Myers have struggled mightily in their limited roles, posting concerning advanced metrics that underscore their difficulties. Both defenders register below 46% in expected goals for percentage (xGF%) at five-on-five, with Myers particularly struggling in high-danger chance situations at just 41.67%.

Myers has managed to appear in only a handful of games this season after suiting up for 36 contests last year, while Benoit’s inconsistency has been an ongoing concern dating back to the previous campaign. Neither player provides the puck-moving ability or transition speed that head coach Craig Berube’s system requires. The Maple Leafs need defenders who can execute clean breakouts and join the rush when opportunities present themselves, yet Benoit and Myers have been frequent culprits in the turnover epidemic plaguing Toronto’s defensive zone exits.

Dakota Mermis currently serves as the team’s lone extra defender on the roster, but his presence alone doesn’t address the fundamental issues. The organization needs to look beyond stopgap measures and evaluate whether younger, more dynamic options can provide both short-term relief and long-term development opportunities. The Maple Leafs’ defensive struggles raise questions about their blue line construction, and the answer might already exist within the organization’s depth.

The timing couldn’t be more critical, as injuries to key players like Auston Matthews have exposed just how thin Toronto’s margin for error has become. When veteran defenders continue making costly mistakes and the team desperately needs contributors who can stabilize the situation, keeping productive AHL performers in the minors becomes increasingly difficult to justify.

Henry Thrun’s impressive start with the Toronto Maple Leafs organization makes him a prime defensive call-up candidate

Henry Thrun arrived in Toronto via trade from the San Jose Sharks on July 10, 2025, in exchange for Ryan Reaves. The 24-year-old left-shot defenseman brought with him a $1 million cap hit through the 2025-26 season and a reputation as a mobile, defensively sound blueliner with untapped potential. His acquisition represented general manager Brad Treliving’s attempt to add depth and flexibility to a blue line that needed both.

Through 13 games with the Marlies this season, Thrun has compiled eight points, including three goals and five assists, demonstrating offensive capabilities that weren’t prominently featured during his time in San Jose. His goals for percentage of 58.6% when on the ice indicates that the Marlies control play more effectively when Thrun is deployed, a stark contrast to the negative possession metrics posted by several NHL roster defenders.

What makes Thrun particularly intriguing is his playing style. He’s described as quiet but strong in transition, possessing the ability to calm situations down before initiating clean breakouts. Standing 6-foot-2 and weighing 212 pounds, Thrun has the size to handle NHL physicality while maintaining the mobility to skate himself out of trouble. His left-shot orientation also provides roster flexibility, as he can slot into various pairings without forcing other defenders out of their natural positions.

Thrun registered 12 points in 49 games with San Jose during the 2024-25 season, but those numbers came while playing on a struggling team that offered limited offensive support. His improved production in Toronto’s system suggests he may have been underutilized or deployed in a defensive-only role that didn’t showcase his full capabilities. The Marlies have clearly benefited from giving him more offensive responsibilities, particularly on the power play where his mobility and passing vision create opportunities.

The transition to Craig Berube’s structured system shouldn’t pose significant challenges for Thrun. Berube emphasizes defenders making smart reads and activating at appropriate times rather than freelancing. Thrun’s conservative yet effective approach aligns well with these principles, as he rarely takes unnecessary risks but capitalizes on legitimate scoring chances. His two-way reliability could make him a trustworthy option for Berube, who values defenders that won’t expose the team to odd-man rushes through poor decision-making.

Thrun’s development trajectory also suggests he possesses additional untapped potential. Originally drafted 101st overall by the Anaheim Ducks in 2019, he spent four seasons at Harvard University before turning professional. His collegiate pedigree indicates strong hockey IQ and positional awareness, attributes that typically translate well to the NHL level. At 24, he’s entering his physical prime and could provide the Maple Leafs with several years of reliable depth defense if given the opportunity to establish himself.

William Villeneuve’s offensive explosion positions him as a Toronto Maple Leafs defensive depth call-up with tremendous upside

William Villeneuve represents one of the most intriguing development stories within the Maple Leafs organization. The 23-year-old right-shot defenseman was selected 122nd overall in the fourth round of the 2020 NHL Draft, and he’s spent the past four seasons steadily improving his game with the Marlies. After posting 25 points in each of his first two professional seasons, Villeneuve exploded for 40 points in 55 games during the 2024-25 campaign, establishing himself as the team’s most productive defenseman.

This season, Villeneuve has continued his impressive trajectory with seven points through 11 games, putting him on pace to surpass his career-high with approximately 45 points over a full season. His offensive production comes primarily through playmaking, as he’s registered seven assists with three being primary helpers that directly led to goals. His 58.6% goals-for percentage mirrors Thrun’s impressive possession metrics and demonstrates his positive impact on overall team performance.

What separates Villeneuve from other offensive-minded prospects is his hockey IQ and spatial awareness. He excels at spotting open teammates and delivering passes that create dangerous scoring chances. His strong skating ability allows him to join rushes as a fourth attacker, forcing opposing defenses to account for an additional threat entering the offensive zone. This mobility proves particularly valuable on the power play, where Villeneuve constantly moves around the ice, creating confusion and opening passing lanes for his teammates.

The right-shot orientation provides additional roster flexibility that shouldn’t be overlooked. The Maple Leafs currently employ primarily left-shot defenders in their top four, with Morgan Rielly, Jake McCabe, and Brandon Carlo all shooting left. Maple Leafs weigh defensive changes as Thrun and Villeneuve push for NHL call-ups, and Villeneuve’s ability to play on either side of the ice gives Berube multiple deployment options without forcing handedness compromises.

Villeneuve’s defensive game has also shown marked improvement, addressing previous concerns about his ability to defend at higher levels. While he occasionally gets caught in transition, his foot speed allows him to recover and minimize damage. He won’t physically dominate opponents along the boards, but he maintains proper positioning and uses active sticks to create turnovers. At 6-foot-2 and 182 pounds, he possesses NHL size but continues working to add strength and physicality to his game.

The Maple Leafs demonstrated their belief in Villeneuve’s progress by signing him to a one-year contract extension on August 5, 2025. While the short-term deal represents more of a prove-it opportunity than a long-term commitment, it maintains organizational control beyond this season as he’ll remain a restricted free agent when the contract expires. This structure provides both sides with flexibility while giving Villeneuve the chance to earn NHL playing time and showcase his readiness for a more substantial contract.

Villeneuve’s playing style aligns well with Berube’s system requirements. The head coach wants defensemen who can move pucks efficiently and activate at appropriate times rather than constantly pinching or taking unnecessary risks. Villeneuve’s decision-making has matured considerably, and he now chooses his offensive opportunities more judiciously. This calculated approach should earn Berube’s trust more quickly than a defender who freelances or abandons defensive responsibilities in pursuit of offense.

Perhaps most importantly, Villeneuve represents the type of prospect development success story that justifies organizational investment in the AHL affiliate. He’s taken incremental steps forward each season, addressing weaknesses while building on strengths. His progression from a raw fourth-round pick to a legitimate NHL call-up candidate demonstrates both personal dedication and effective coaching from the Marlies staff.

Comparing Toronto Maple Leafs defensive depth call-ups Henry Thrun and William Villeneuve to current roster options

The statistical comparison between Thrun, Villeneuve, and current roster options like Benoit and Myers reveals a stark disparity in production and effectiveness. Through their first 13 Marlies games, Thrun and Villeneuve have combined for 16 points, dwarfing the two combined points registered by Benoit and Myers at the NHL level. While AHL production doesn’t automatically translate to NHL success, the magnitude of the difference suggests both prospects are outgrowing their current assignments.

Advanced metrics paint an even more compelling picture. Benoit’s 45.29% xGF% and 43.98% scoring chance for percentage (SCF%) at five-on-five indicate the Maple Leafs are significantly out-chanced when he’s on the ice. Myers posts similarly concerning numbers with a 45.89% xGF% and 44.44% SCF%. These figures demonstrate that both defenders struggle to generate offense while also failing to suppress opponent scoring chances, creating a double-edged problem for a team already allowing the league’s most goals.

By contrast, both Thrun and Villeneuve maintain positive possession metrics in the AHL, suggesting they drive play in the right direction more often than not. Their combined 58.6% goals-for percentage indicates the Marlies control over half of the goals scored when either player is on the ice. While the quality of competition differs between leagues, the trend lines point decidedly in favor of the prospects rather than the struggling veterans.

The stylistic differences also merit consideration. Benoit brings physicality and a defensive-first mentality, but his limited mobility and poor puck skills create problems in transition. The modern NHL increasingly values defenders who can skate, pass, and contribute to offensive sequences, making Benoit’s skillset somewhat outdated for Berube’s system requirements. Myers offers slightly better mobility but lacks consistency and has bounced between the NHL and AHL throughout his career without establishing himself at either level.

Thrun and Villeneuve both provide superior puck-moving ability and transition skills. They can execute the clean breakouts and zone exits that have eluded Toronto’s current defensive corps, potentially reducing the turnover rate that has directly contributed to numerous goals against. Their willingness to join rushes and create offensive chances also addresses Toronto’s need for more balanced scoring throughout the lineup rather than relying exclusively on star forwards.

The age factor shouldn’t be dismissed either. Thrun at 24 and Villeneuve at 23 are entering their prime development years, while Benoit (27) and Myers (28) are established NHL veterans whose current performance likely represents their ceiling. Giving younger players opportunities not only addresses immediate needs but also provides valuable data for long-term roster construction decisions.

What Toronto Maple Leafs defensive depth call-ups Henry Thrun and William Villeneuve bring to the NHL level

Both Thrun and Villeneuve offer specific attributes that directly address Toronto’s most pressing defensive issues. The Maple Leafs rank among the league’s worst teams in transition defense, consistently surrendering odd-man rushes and breakaway opportunities through poor zone exits and turnovers. Both prospects excel at exactly these transition elements, suggesting they could provide immediate improvement in Toronto’s most problematic area.

Thrun’s calm demeanor under pressure makes him particularly valuable in high-stress situations. Rather than panicking when forechecked aggressively, he maintains poise and finds outlets for safe breakouts. His passing accuracy and willingness to skate pucks out of danger zones reduce the likelihood of turnovers in vulnerable areas. These qualities become especially important when facing forechecking systems designed to force mistakes and generate transition offense.

Villeneuve’s offensive creativity offers a different dimension. His ability to quarterback power plays could prove invaluable for a Toronto special teams unit that needs more production from the point. His constant movement and passing vision create opportunities that static defenders cannot generate. If the Maple Leafs lose a top-four defender to injury—always a possibility given the physical nature of the season—Villeneuve’s skill set allows him to fill multiple roles rather than being limited to bottom-pairing duties.

Both players also bring youth and energy that could prove contagious for a struggling team. Sometimes roster shake-ups serve more than just tactical purposes; they send messages about accountability and performance standards. Promoting productive AHL players while demoting struggling veterans demonstrates organizational commitment to meritocracy and might motivate other players to elevate their games.

The financial flexibility both prospects provide shouldn’t be overlooked either. Thrun carries a $1 million cap hit, while Villeneuve plays on an entry-level contract at even less expense. In a salary cap environment where every dollar matters, finding inexpensive contributors allows teams to allocate resources elsewhere or maintain flexibility for deadline acquisitions. Their presence on the roster creates financial breathing room that veteran depth defenders don’t provide.

Craig Berube’s reputation for player development also factors into this equation. The veteran coach has successfully integrated young defenders into NHL lineups throughout his career, providing structured systems and clear expectations that help prospects transition smoothly. Both Thrun and Villeneuve possess the hockey intelligence and work ethic that Berube typically values, suggesting they’d respond well to his coaching style.

The psychological impact of earning an NHL call-up also drives development. Both players have worked diligently in the AHL, progressively improving their games and waiting patiently for opportunities. Rewarding that dedication with NHL ice time validates their efforts and provides motivation to continue developing. Conversely, watching less productive veterans maintain roster spots ahead of them could breed frustration and resentment.

As the Maple Leafs navigate a challenging stretch of their schedule with injuries mounting and defensive issues persisting, the time has arrived to evaluate internal options. Both Henry Thrun and William Villeneuve have earned consideration through consistent AHL production and demonstrated skills that address Toronto’s specific needs. Whether they receive call-ups may ultimately determine if the Maple Leafs can stabilize their defensive play and return to contention, or if they’ll continue struggling with the same personnel making the same mistakes. The solution to Toronto’s defensive crisis might not require trades or major acquisitions—it might simply require looking down the highway to the Marlies and promoting the players who’ve already proven they deserve a chance.
