Like he so often was during his glory years.
For Chayka, Hiller and senior advisor Mats Sundin, just as important as Matthews' production on the ice is his buy-in off it, in terms of the direction the team's brain trust wants the franchise to go in.
Compare that to the vibe of uncertainty surrounding him during the Maple Leafs exit meetings in April when there was no GM and, at the time, no apparent blueprint. Did he want to stay with the Maple Leafs with two seasons remaining on the four-year, $53 million contract ($13.25 million average annual value) he signed on Aug. 25, 2023?
"I can't predict the future," he told reporters on April 16. "There are steps that have to take place. They've got to hire new leadership in management. I don't really know. I can't really predict the future."
Half a year later, the narrative around Matthews has significantly changed for the positive. Chayka, Sundin and, subsequently, Hiller, were hired; the roster has gone through a significant upheaval featuring additions like forwards Jack Roslovic, Nick Paul and Kirill Marchenko, defenseman Darren Raddysh, and goalie Sergei Bobrovsky; and the Maple Leafs won the Draft Lottery, which eventually netted them No. 1 pick Gavin McKenna.
"With John here now, I really like what he's done this summer," Matthews said during the opening of training camp last month. "I think he's made some great changes, brought in some great people, some great players, great outside hires as well, and it's been great so far meeting everybody.
"It's been super positive. Great energy at the rink."
And away from it, thanks in part to Matthews who appears to be embracing his captaincy like never before.
In the days leading up to the regular season, he hosted players and management at his home during a team-bonding trip to Arizona. He, like teammate John Tavares, has taken McKenna under his wing, including having the rookie over for a "sleepover" Sunday to watch football and have sandwiches. Earlier that same day, it was Matthews who led his teammates on the ice in what was supposed to be an optional practice.
All the while, he seems more relaxed, more upbeat and certainly more available to reporters. In summation: he seems to be more comfortable in his own skin.
Hiller was an assistant on then-coach Mike Babcock's staff from 2015-19 and had the chance to work with Matthews after the Maple Leafs selected him No. 1 in the 2016 NHL Draft. A decade later, he's impressed how Matthews' leadership has grown and said he's fully worthy of wearing the "C" for the Maple Leafs.
"It's everything I could've hoped for," Hiller said. "Spent three years with him when he was a young guy and I felt I could just see someday him being the captain of the Toronto Maple Leafs and leading and playing the game the right way."
