Mitch Marner’s exit reshapes Toronto’s top six as training camp opens. Matthews steps into a leadership role, while new wingers like Max Domi and Matias Maccelli are pegged to join him, with Matthew Knies at left wing. Vegas counters with Marner teamed with Jack Eichel, altering both rosters’ offensive dynamics. Toronto adds depth through Dakota Joshua, Nicolas Roy, Michael Pezzetta and Travis Boyd, plus a possible rookie push from Easton Cowan. Domi’s day-to-day injury status and Stolarz contract talks headline the business side as the Leafs pursue a refreshed core ahead of the Oct. 8 season opener versus Montreal.

Fantasy angles center on who fills Marner’s production hole, how Matthews’ line chemistry develops with the newcomer trio, and which Leafs players earn expanded roles to push for 70+ points. The club signals a forward-focused reset while keeping the core defense and goal-tending intact, aiming to translate a deeper roster into more consistent postseason outcomes. Meanwhile, Vancouver’s Joshua swap and the Leafs’ depth moves set up a crowded camp battle with real fantasy upside.
