The Indianapolis Colts have carved out a unique spot in the NFL. The team is sandwiched between the Cincinnati Bengals and the Chicago Bears from southeast to northwest, and the Colts get to own the state of Indiana. Where taxes are paid is important, after all.
That is because an NFL team provides jobs not only for the organization, but for the city that is home to its stadium. The jobs needed to host a football game are great, of course. Concessions, parking, and road management all play a part on gameday. That naturally creates a built-in structure for a long-term fanbase.
