Story summary

In the past four months, John Chayka and Mats Sundin have significantly revamped the Toronto Maple Leafs, following their failure to make the playoffs last spring. Their partnership includes signing goaltender Sergei Bobrovsky, who is now 38 years old; acquiring defenseman Darren Raddysh for his puck-moving skills; and drafting Gavin McKenna, a prospect who unexpectedly fell to the Leafs in the draft lottery. Chayka, the team's general manager, acknowledges Sundin’s critical role, saying he wouldn’t have taken the job without him. Sundin relocated from Stockholm with his family for this opportunity, emphasizing its importance and rarity. This unique management duo aims to restore the team’s aspirations through collaborative decision-making, setting a precedent in NHL governance.

🔮 Someone I always tried to avoid, would cross the street whenever I clocked him.
🔮 Beals, testifying at a coroner’s inquest Friday into the death of her daughter in May 2020, didn’t like it, not one bit, when coroner counsel Roger Shallow asked gently, respectfully, if she could hear the words she spoke, captured on security video.
🔮 I wish I could.
🔮 Obviously you could think what if this, what if that, but it is what it is.
🔮 I’m willing to play whatever role this team wants
🔮 It was Toronto’s third win and Bobrovsky’s first, aided by a five-point night from William Nylander and a two-goal third period from Auston Matthews, his empty-netter with 39 seconds left utterly deflating the crowd, although their team had flatlined long before.
🔮 Which, it’s hoped, will help elevate Stolarz to far better than the .893 save percentage he posted last season.
🔮 Yet still the outfit Marner poured his heart into alongside Auston Matthews, William Nylander, John Tavares and Morgan Rielly.
🔮 What matters most, even in the early sprout of a season: In the first skirmish of the Battle of Ontario, Ottawa knocked off Toronto 3-2, drawing first blood in what surely will be a frenzied wrangle for playoff inclusion in the fiercely contested Atlantic Division.
🔮 Bang-on prophecy: That William Nylander, on his first shift of the first game of the year (48 seconds after puck drop), would score Toronto’s first goal against the visiting Montreal Canadiens.

Narrative

In the busy-busy past four months, Chayka and Sundin have extensively reoriented a Leafs team that unforgivably didn’t make the playoffs last spring, primarily by reeling in goaltending luminary Sergei Bobrovsky (his age, turning 38 on Sunday, a contractual gamble), defenceman Darren Raddysh (poised puck movement, heavy right-handed point shot to quarterback the power play), overhauling the bottom-six bracket, and No. 1 draft pick Gavin McKenna, who fell into Toronto’s lap via the draft lottery.
