The Buffalo Bills aren’t in the biggest market.
The fans know this and make up for it by being loyal and vocal through and through.
There is currently a bracket-style Twitter contest deciding the best fan base in the entire NFL. At the time of this post going up, the Bills have a chance to move on to the final four of the bracket.
This should be no surprise to anyone who follows the team. Competitions based on Twitter polls are sometimes criticized for being a popularity contest. But if a team with a smaller following like the Bills takes down a team from a giant city, then that is a telling sign of overall popularity.
