I found this site that ranks cities for championships (football, baseball, basketball, hockey). They use a formula using number of championships, how long a franchise has been around and how many teams were in the league when a team won a championship (you get more points for winning a championship NOW then you did 40 years ago when there was less teams)............very interesting:
