Check out this site from Noah Veltman (via Ben Alamar) dividing the U.S. into regions nearest various stadiums. Click on the NFL logo atop the page to filter for NFL stadiums. Checking the box to combine the San Francisco and Oakland markets also helps.
Teams market themselves beyond these narrowly defined regions, of course, but I find it interesting to see how loyalties would fall by latitude and longitude. Veltman used this Google document with precise stadium locations to generate the map.
I'd like to see populations for each of the defined regions.
