As a stats geek, I'm not happy with answers that rely on goats and curses. Nor can I accept that fans of one team have suffered too terribly when the other pro teams in that same city have racked up one championship after another. (Jets fans, I'm looking at you.)

In short, here's how it works: A city gets one point for each season played by its pro sports teams since the last calendar year in which one of those teams won a championship.
