19. Arizona Cardinals
The Cardinals can take pride in being the oldest football club in America founded in 1898. Their fans are the lowest ranked on our list not because of the lack in awesomeness but because of the statistics of sold tickets. All hard core fans wear team colors and those are cardinal red, white, black and yellow. The creative ones pair their jerseys with face paint and colorful wigs trying to resemble to cardinal. Team mascot is Big Red.
