As a diehard Dallas Cowboy's fan I was ready to be boasting about this all day, but they didn't even come into the top five. What the hell.

How does one determine the best fanbase in the NFL? If it were the biggest, I am pretty sure the Dallas Cowboys would have that one in the bag. They used a formula of attendance, television ratings, merchandise sales and percentage of population that watched or attended their hometown team's games. I do admit the Packers do have a very die hard fanbase, but what else can you do in Green Bay?

The other thing that makes me mad about this, the tie for seventh place. Really, you just had to add to the fire Forbes of more stuff for Steelers and Cowboys fans to argue about. I am also guessing Forbes did not factor in diehard fans with tattoos because I would have gotten the Cowboys some point on that one.
