The Geography of NFL Fandom

NFL football fans can "like" teams on Facebook. That company produced this map showing which teams were liked more than any others in a county. You can see a larger version here.
It's interesting that the Raiders are still popular in Los Angeles, though they are now in Oakland. There's also a big swath of Cowboy country in Nevada. One county in central Missouri also has a lot of fans of the Dallas Cowboys. That looks like Pulaski County, if I'm reading the map correctly.
We would like to note that the depiction of Alabama is misleading. The state doesn't belong to the New Orleans Saints, but the Crimson Tide and the Tigers--college football teams.
