Outright move-in? Sure. But grease the skids with a few hundred-mil? If the New York Metro can host 3 NHL teams, there's no reason GTO can't handle two.
But even if you leave Toronto out of it, there are markets that want an NHL team and the Sabres would be worth double in any of them. One city that doesn't get talked about much is Houston. #4 US market and a history of good support for the minor league Aeros. You know Quebec City is dying for a team. Maybe Hartford again? Kansas City has a new arena. The point is never take having the Sabres or Bills in Buffalo for granted. The vultures never stop circling.
What market with a major league franchise is lower than us? I can't think of one.
