Nah... the Islanders should move to Seattle.
If I had to make a list of NHL teams that should move, the Isles wouldn't crack the top-5.
Phoenix
Atlanta
Tampa Bay
Florida
Nashville (strictly for $$$ reasons)
And while I love the idea of puck in the Emerald City, I honestly would want Hartford, Quebec and Winnipeg to get their teams back first (since they should have never left in the first place!) and then KC.
