Mitch Marner’s Vegas dominance exposes what went wrong in Toronto

Mitch Marner’s playoff breakout with the Vegas Golden Knights has forced a hard conversation in Toronto. Through 13 playoff games, Marner leads the NHL with 19 points, owns a plus-13 rating, and has become the engine behind Vegas’ run to the Western Conference Final against the Colorado Avalanche.

The same player, once branded as a postseason disappointment with the Toronto Maple Leafs, now looks like a Conn Smythe favorite.

The numbers alone are difficult for Toronto to ignore. Marner already has seven playoff goals, more than double his best postseason total with the Leafs. He has delivered game-breaking moments, including a second-round hat trick against Anaheim and a between-the-legs breakaway finish in Game 6. Vegas has also leaned on him in every situation, where he leads the playoffs with four shorthanded points.

But the biggest difference is not only statistical. It is structural.

Mitch Marner was always playing ‘in service of Matthews’

ESPN’s Greg Wyshynski recently pointed out the frustration many observers share. “He’s different, and it can’t just be the Toronto media, and it just can’t be the fans,” Wyshynski said while discussing Marner’s postseason transformation.

That answer may sit inside the way Vegas distributes responsibility. Veteran analyst Jeff Marek referenced skills coach Adam Oates when explaining why Marner looks freer in Vegas.

“It’s not my theory. It’s Adam Oates’ theory, and I believe it,” Marek said. “In Toronto, he was expected to do everything for everybody. Go fetch this puck. Go make this entry. Go do this. Everything was like, ‘Mitch is gonna do this to set up Matthews, who is gonna score.’ Right?

“Everything was always gonna be in service of Matthews, and Mitch had to go play fetch for everybody.”

That workload mattered. In Toronto, Marner often carried the puck through the neutral zone, managed retrievals, drove transition play, and created offense for Auston Matthews. When playoff checking tightened, the pressure multiplied. Every failed possession became magnified in the Toronto market.

Vegas built a system that supports Marner

Vegas spreads those demands across elite two-way players like William Karlsson, Mark Stone, and Jack Eichel. Marner no longer has to initiate every sequence.

“[Now] he looks great with William Karlsson, and William Karlsson is one of the best two-way centers in the entire NHL. We know that,” Marek said. “People are doing things for Mitch. It’s not just Mitch doing things for everybody else, specifically, you know, just go find the puck, get the puck, hand the puck, get the puck, and get it to Matthews, and he is going to shoot.

“In Vegas, it’s different man. He’s not expected to do all of that. We’ve got a William Karlsson, we’ve got a Mark Stone, we’ve got a Jack Eichel. You don’t have to do all that stuff that you did in Toronto that wore you out, mentally and physically.”

Toronto’s roster imbalance came to the surface

The 2025-26 regular season has exposed a long-standing issue with Toronto’s core construction. The Leafs relied too heavily on individual creation from a small group of stars without enough insulation underneath them. And when they failed to create the desired offense, the Leafs missed the playoffs with a 32-36-14 record.

Vegas, by contrast, attacks in layers and has depth. Marner can create offense without carrying the full emotional and tactical burden of the team.

That does not erase Toronto’s criticism entirely. Marner’s playoff record with the Leafs included long scoring droughts in elimination games, and the scrutiny around his contract never disappeared after his 2019 extension. But his current run suggests the environment in Toronto amplified every weakness while limiting the parts of his game that thrive under support and structure.

Vegas did not change who Marner is as a player. It changed what he was asked to survive.
