NFL Empires: 1958

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 1957 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 1958 season:

In "The Greatest Game Ever Played", Baltimore (medium blue) beat New York (dark blue) at Yankee stadium for the championship. It was the first sudden death overtime NFL playoff game. The Chicago Bears (light blue) had a good imperial resurgence this year, coming in second in the West. Los Angeles (red) came in third in the West. All told, the Western Conference controlled about 90% of the land by the end of the season. Eastern second place Cleveland (brown) had barely more than Western fifth place Detroit (purple).

Here is the map before the season started:

'Twas the year of blue.
