On the sentiment side, the Colts have swapped places with Cincinnati Bengals too, moving from third to first as the most negative fandom while the Bengals slip to third.
The most positive fandoms, however, have stayed consistent: Tampa Bay Buccaneers, Arizona Cardinals and Denver Broncos occupy the same top three positions as last year, though all three fandoms' positive shares have eased slightly.
On the polite side, Los Angeles Chargers topped last year's rankings, but have been overtaken this year by the Buffalo Bills.
