NFL Empires: 1957

This is a continuation of my "empire" maps (where victors take the territory of the losers) of the NFL. Different than most such imperialism sports maps, instead of gaining all the loser's land from a victory home or away, the victor only gets territory for an away victory, and just two-thirds of it (or one-third for an away tie).

There were no changes to teams from the 1956 season.

My data was from Pro Football Reference and most of the logos from SportsLogos.net and Sports Ecyclopedia.

Here then is the map of the NFL empires after the 1957 season:

Detroit (purple) won the championship game over Cleveland (brown), but it was played in Detroit so no land was gained. In the Western Conference, Detroit and San Francisco (burgundy) tied for first, so they had a playoff game. It was played in San Francisco, so Detroit actually gained most of their land in that one game. Also prominent on the map is Baltimore (medium blue), who came in third in the West. Washington (gold) gained a good empire even though they had a losing record, fourth in the East, because they beat the Chicago Bears (light blue) in Chicago to get a piece of that crumbling empire. Second in the East was New York (dark blue), who lost most of their empire with a couple late home losses.

Here is the map before the season started:

Bad year for the Bears and that other Chicago team.
