Fans of the Pittsburgh Steelers are said to be the most loyal and best fans in the NFL, with the the Steelers' unbelievable sellout streak of 299 chronological games as the reasoning behind that statement.
They have an amazing number of fans in other areas around the country most likely due to the the collapse of the steel industry, and then the spreading out of Pittsburgh citizens for career opportunities, or it could be due to their success in the 1970s.
Being a fan, I have many reasons to be proud of my football team. They have won the most Super Bowls and are the current reigning champions. We also have the NFL's leading defense, an awesome quarterback, and a very speedy running back. Not to mention countless other amazing players.
When someone asks me who I am a fan of, (and in Texas/Arkansas, it's expected to be a Cowboys or Saints fan), I am always proud to say that I am a fan of the Pittsburgh Steelers, and that nothing can ever change that.
