What happened: The Philadelphia Flyers tendered Leo Carlsson a five-year, $90 million offer sheet carrying an $18 million annual cap hit. The Anaheim Ducks have seven days to match or accept four first-round picks as compensation.

Why it matters: Matching would retain Anaheim's franchise center while reshaping its salary structure around a record-setting deal. Declining would cost the Ducks a proven young star but replenish their draft capital, with Pavel Mintyukov and other young players also requiring contract planning.

What to watch: Anaheim's decision before the seven-day window closes will determine whether Carlsson remains with the Ducks or joins Philadelphia. Mintyukov's contract situation and Shane Wright's future are additional offseason developments to monitor.
