NFL Empires: 1961

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).

Before the season, Minnesota joined the league. They gained the land within a 100-mile radius of their new capital. Dallas were moved from the Western Conference to the East, where they've been ever since.

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 1961 season:

Green Bay (kelly green) beat New York (dark blue) for the championship, but the game was in Green Bay, so no land was won. Baltimore (medium blue) gained control of a decent empire, despite a mediocre third place in the West. Detroit (gray purple) and Philadelphia (dark green) earned second place in each conference, but neither were consistent at home, so they couldn't accumulate much land. Overall, this season had a high degree of parity, with lower teams beating higher teams and pairs of teams beating each other in the other's home stadium.

Here is the map before the season started:

Lots of land swapping going on...
