Are the Toronto Maple Leafs missing Mitch Marner?

After a long offseason, the Toronto Maple Leafs have had a very mediocre start, very similar to how they’ve opened the season over the past couple of years. Playing nine games this year, they sit at 4–4–1, 6th in the Atlantic division, and are searching for stability. The results have been mixed, and so has the effort.

The tension really started to build following a defeat to the Seattle Kraken, where, after the game, goaltender Anthony Stolarz called out the team’s defensive commitment to him as the Leafs’ netminder. They followed that performance with another defeat to former head coach Sheldon Keefe and the New Jersey Devils. This loss further amplified early concerns, as Toronto’s offence has struggled to generate sustained pressure, and its overall play is lacking cohesion. Why could this be? The loss of Mitch Marner.

Life without Mitch

For many years, Marner has served as Toronto’s offensive catalyst as one of the league’s most complete wingers. His playmaking, vision, and defensive awareness tied together the Leafs’ top unit and power play. Without him, the attack loses much of its creativity and unpredictability. A lot of the zone entries are less controlled, puck movement is less fluid, and the top lines’ chemistry has noticeably diminished. Last season, Marner was the only Leaf to hit over 85 points, putting up 102 points. And so far in Vegas, Marner has put up 10 points in his first nine games with the club. 

The team’s overall numbers support the drop-off. Toronto’s power play currently ranks 29th in the NHL with 13%. The puck movement that typically runs through Marner’s stick has been replaced by static positioning and predictable shot selections. Opponents have been able to collapse on Auston Matthews, taking away his primary shooting lane and forcing the Leafs to the perimeter.

The impact on the defensive side of the puck has been the same. The Leafs currently average 3.67 goals against, which ranks 27th in the National Hockey League. While Marner’s offensive skill draws the headlines, his defensive instincts often provide crucial support for Toronto’s blue line. His ability to disrupt plays in transition and relieve pressure in the defensive zone has long covered up weaknesses in the team structure. Without that layer of reliability, Toronto’s exits have become messy, leading to prolonged defensive zone time and higher-quality scoring chances against.

The replacements

Management hoped that the offseason additions would help mitigate that kind of gap, with Dakota Joshua, Mattias Maccelli, and Nicolas Roy being brought in to add depth, secondary scoring, and more responsibility to a play. Collectively, they have produced only nine points so far this season. Joshua has brought a physical edge, Maccelli has brought flashes of skill, and Roy has stabilized the bottom-six, but none have been able to replicate the impact or creativity that Marner brought.

The lack of production from the supporting cast underscores a long-standing challenge for Toronto: maintaining consistency when one of its star forwards is unavailable. The Leafs’ offence remains heavily reliant on its core players, and without Marner, the system has struggled to generate offence by committee.

Head coach Craig Berube has downplayed the early-season record, stressing that the group needs time to develop chemistry and learn new systems. Still, the underlying issues are difficult to ignore. Toronto has too often looked reactive rather than proactive, chasing games instead of dictating play. The defensive zone coverage remains loose, the neutral zone pressure is inconsistent, and the puck management has been unreliable

Glue guy

Beyond tactics, Marner’s influence extends to intangibles. His competence, communication, and confidence often set the tone for the team. Without him in the lineup, the energy has noticeably been missing, as he was a very big locker room guy.

Giving the Leafs credit, there are positive signs with William Nylander continuing to produce and John Tavares proving he still has it. The team has shown flashes of the high-tempo, possession-driven hockey that has made them dangerous in recent seasons. But without Marner, those stretches have been short-lived.

The Leafs must find ways to generate offence without overextending their top line. They need to find what works for them to be a successful team.  Losing a guy who can do everything is huge, and for this team, it seems to be affecting them heavily. Nonetheless, it is very early in the season, and things could change, but from what we have seen so far, the Leafs are missing that piece.
