Here's a bit of trivia -- the Green Bay Packers is the only team in the National Football League that is owned publicly. The significance of that, of course, is that the team won't pick up and move to another city because its shareholders (largely Green Bay fans) would throw an absolute fit.
Good idea, huh? What could be more disappointing than seeing your favorite team pick up and leave to another city? Packers fans don't have to worry about that, while other NFL fans do have to be worried. After all, what did St. Louis Cardinals, Houston Oilers, Baltimore Colts fans, etc. do when their teams headed for other cities?
