NFL Empires: 1921

I recently saw "empire" maps for professional and college sports, where victors take the territory of the losers. They seem to usually be reset every year, since they get dominated by a few teams, or just one. But I decided it made more sense that the victor only gets territory for an away victory (and not winning at home), and instead of all the land, just two-thirds (and one-third for an away tie).

I thus decided I had to do this with a long-existing league and start at the very beginning. This then is the second season of the NFL, starting where the first season ended and adding new teams with new territory (taking a 100-mile radius, except only halfway to a "capital" city).

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

Here then is the map of the NFL empires after the 1921 season (when it was called the APFA):

Canton (red) really looks like they did well this season, but the Chicago Staleys (light blue) were crowned champions and Canton were also behind Buffalo (purple) and Akron (pale green). The teams did not play an even number of home and away games, so a team like Canton, who played three home games and seven away games (finishing with six away games), can take territory and never put it at risk by losing. Meanwhile, the Staleys played all eleven games at home (none away!), so they can only lose territory and gain none. It might be good for their trophy case, but it's bad in this empire world.

Here is the map at the beginning of 1921:

Seven of these teams played four or fewer games.
