Every NFL fanbase is great. And terrible.
Each team's fanbase is full of both wonderful people and folks who should be kept overnight in the stadium prison as well as hardcore football junkies, casual supporters, bandwagon jumpers, students of the game, know-it-alls, comment thread loudmouths, tailgate gourmands, Pollyannas, nihilists, fair-weather friends and old-timers with "buried in my jersey" written into their wills.
That makes ranking fanbases more of an art than a science, which is why Emory University marketing professor Mike Lewis whiffed so badly with his data-driven rankings last week. There's more to evaluating fan loyalty and quality than counting attendance figures, revenue and Twitter followers.
