You look at a place like Green Bay that's economy that's pretty much based off the Packers. As I am aware they're supported by the entire state of Wisconsin. Hershey is not only known for Chocolate, but the Hershey Bears as well, or as I like to call them: The Montreal Canadiens of the AHL. Regina has the home field to the Saskatchewan Roughriders, as in the same case as Green Bay is supported by the entire Province of Saskatchewan. We'll just pretend a small city has a successful hockey team in a Canadian City, we'll say St. John's as they don't really have any major sports franchise other than the Growlers. They get an NHL team with star players on every single line and manage to be successful for twenty years in a row winning fifteen cups in twenty seasons, where they sell out every single game to the point where people are coming across the globe to watch them play. How much would that fix their economy?
