With the season starting up this website will tell you what game is being shown nationally and where. I used this site a lot last year since I go to school in St. Louis. It's really helpful if you're traveling or out of the KC market. If you scroll down to the bottom of the page you'll see a map that shows what is being shown and where. Right now it shows an MLB game. But as we get into the season these types of maps should be available for all the nationally televised NFL games(it was last year at least). I think it might even show you what's being shown in the market you are in regardless if it's nationally televised.
