Seattle should be a good NHL market. They're doing the right thing with the arena putting it in an area convenient for fans. Phoenix is not a bad market but the arena is placed so that it's difficult for fans to go. Hopefully there will be two expansion teams for Seattle and Quebec or Hamilton.
Edmonton should keep their market but it will never be a big money making location. Teams need revenue streams other than attendance to make it. I'd hate to see fans lose their team and that includes snobby Canadian ones.
