This is how the NFL would look if the conferences and divisions were divided by team name. I've divided the league into two conferences, the Animal Football Conference and the Human Football Conference. I had to change a couple of team names to make it work, but I kept the changes minimal.
AFC
CATS: Bengals, Lions, Panthers, Jaguars
BIRDS: Cardinals, Ravens, Falcons, Eagles
FARM: Colts, Rams, Bills, Brown Dogs*
WILD: Bears, Broncos, Dolphins, Seahawks**
HFC
OCCUPATIONS: Steelers, Packers, Cowboys, Jet Pilots***
ETHNICITY: Redskins, Chiefs, Texans, Vikings
HISTORY: 49ers, Patriots, Raiders, Buccaneers
MYTHOLOGY: Giants, Titans, Saints, Zeus' Lightning Bolts****
And there you have it! Any better ideas? Let me know in the comments below.
*I'm not sure what the Browns are supposed to be, but I know of the famous "Dawg Pound", and I needed another animal team.
**There were too many bird teams, and the Seahawks seemed to fit with the WILD division. C'mon... It's not anymore absurd than Dallas playing in the NFC East now, is it?
***Same problem as with the Browns. I did my best.
****Ok, ok. It's a stretch, but it fit in the Mythology division. Besides, does anyone really know what a "Charger" is supposed to be?
