The "silver lining" for the Oilers is that they should have another run at it in 2024-25 before having to start truly shuffling pieces. They do have a lot of free agents this year, but almost none of them are key players. They should be able to keep Foegele and Janmark if they want to (although Foegele has warranted a decent raise). Henrique is probably the most notable name they lose, and he was only a trade deadline rental. They're not going to miss Corey Perry, Connor Brown, or Sam Gagner.
Following 2025, with Draisalt (UFA) and Bouchard (RFA) up for new deals, is when the pain will really set in and they'll have to make some tougher choices.
