For five years, Emory University has used data to rank the fans of every team in the NFL.
It calls it the "NFL Fan Base and Brand Rankings."
In 2015, Cardinals fans were ranked No. 19. In 2016, they slipped to No. 25.
This year they are worse.
The study has fans of Arizona's NFL team at No. 27.
Dallas Cowboys fans lead the list, followed by New England Patriots and Philadelphia Eagles fans.
Kansas City Chiefs fans are the worst in the rankings, with Los Angeles Rams and Tennessee Titans fans right before them.
