I would say that the amount of discussion about the Chiefs is miniscule in comparison to the other AFC East teams.
Look no further than the annual Jets Suck thread for proof.
In terms of the Chiefs, keep in mind these factors:
- They are the Super Bowl champions; 31 other NFL fan bases know about them and comment on them.
- They are the conference champions; 15 other AFC fan bases know about them and comment on them.
- There was an incredible amount of media attention devoted to KC, thanks to Taylor Swift.
- There is a Chiefs fan who is one of this forum's more prolific posters.
Now let's compare how much other fan bases talked about the Patriots for the first two decades of this century.
You want to see obsession?
Look at fan forums of the Steelers, Colts, Chargers, Bills, Jets, Dolphins, etc. back during that time period.
