What happened: Auston Matthews opened training camp saying he is ready for a new season after a difficult year in Toronto. The Maple Leafs begin camp with a reshaped roster and a new coach as Matthews centers the club's next phase.

Why it matters: The reset carries weight after Toronto missed the playoffs for the first time since 2016 last season. It also extends an offseason that had Matthews building chemistry ahead of camp, putting early camp work under immediate scrutiny.

What to watch: Watch how Matthews is deployed as camp opens and how quickly the new roster settles into defined roles. Early preseason usage should offer the first clues about Toronto's approach for the upcoming season.
