I don't see it. They don't have any top-end talent, they are locked into a disappointing goaltender, and they have Francis and Hakstol as GM and coach. Which difference-making UFA is going to sign with them?
They are way behind Los Angeles and Anaheim in terms of prospect pool.
They don't have anything approaching McDrai, EichStone, or whatever Calgary's top 6 will look post free agency.
Vancouver has a difficult cap situation going forward, but there were playing at a playoff pace under Boudreau.
I think San Jose is pretty much the only team in the Pacific with bleaker medium-term prospects than Seattle.
