As open as I am to EK back in Ottawa (especially if another team is involved and we can somehow finesse him for $4-5 million aav per year, I don't see the Sharks being able to move him unless they can find buyers for other vets that are signed long term.
Grier needs to find buyers for Couture, Vlasic, and maybe even Hertl. Sharks need a complete rehaul, acquire draft picks, get lucky with the lotto and hope that by the time the retaining years on any contracts they have left, they can sign new talent to good deals.
Unless SJS figures out what they want to do long term (rehaul, retool, try to compete with their mediocre roster), they're kinda screwed and I can't imagine they'll be able to move EK
