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.

Florida Panthers eye a third straight Cup, but health and cap pressures loom as Tkachuk recovers and depth is tested. The league-wide preview hinges on goaltending certainty, growth from young cores, and high-stakes off-season moves—from Swayman’s bid to reclaim No.1 in Boston to Hughes’ health in New Jersey and Marner’s Vegas exit in Toronto.

Beyond those headline questions, the piece assesses defensive pivots in Vegas, depth shifts in Minnesota with Kaprizov’s contract talk, and young guns like Demidov in Montreal and Celebrini in San Jose eyeing breakout years. ESPN also maps out 100 exclusive games and a rich out-of-market package as fans plot fantasy rosters.

Maple Leafs add Matias Maccelli to the mix, eyeing a likely right-wing slot beside Auston Matthews and Matthew Knies after Marner’s move to Vegas. Newcomers Nicolas Roy, Dakota Joshua, and Michael Pezzetta bring size, grit, and versatility, while Maccelli aims to prove he can contribute on both ends. Training camp will decide how the rotation threads together, with the lineup shifting to adapt to Toronto’s revamped forward corps.

Toronto’s new depth pictures a bigger, tougher group with Roy handling PK/PP duties, Joshua bringing physicality and scoring touch, and Pezzetta providing an edge for the fourth line. The Leafs will chase a deeper, more balanced attack this season, and fantasy managers should monitor how quickly these newcomers earn roles and power-play time.
