The true test of any fan base is not size, or volume, or happiness. The true test of fandom is loyalty. Can you stay with your team, through the hardest times, to be rewarded in the best of times? It is loyalty that makes a fan, and it is the fandom that imbues them in the experience.
If loyalty is the test of a fan base, then no fanbase has been tested more than that of the Washington Redskins. Once a perennial winner, and a three-time Super Bowl winning team, the Redskins have fallen into the depths of despair, and for twenty years, they have remained there, save for brief, misleading glimpses of hope.
