What happened: Toronto Maple Leafs GM John Chayka has already reshaped the roster with an offseason trade involving the Philadelphia Flyers. Speculation now centers on whether defenseman Morgan Rielly and forward Matthew Knies could be the next core pieces moved if Chayka pursues another significant deal this summer.

Why it matters: Rielly and Knies represent very different assets — a veteran top-pairing defenseman with term and a young, controllable scoring winger — so moving either would signal how aggressively Toronto intends to retool. Any Rielly trade is complicated by his no-move clause, which he has not waived, giving him control over any destination.

What to watch: Watch whether Toronto opens formal trade talks before the new league year and whether Rielly signals any willingness to waive his no-move clause. Knies' status as a restricted free agent or extension candidate will also shape how the Maple Leafs value him in any package.
