Cowboys fans aren't nearly as rabid as Eagles and Steelers fans, but the Cowboys have more of a worldwide audience. If you stay in the team hotel, you'll see something pretty remarkable. No matter where the Cowboys show up (even Appleton, Wis.), there are at least 30 fans waiting for them in the lobby. Texas Stadium is iconic because of the hole in the roof, but now it's simply a dump. This isn't a fan base that feels a great deal of hatred for certain teams or players. In fact, I think Texas Stadium is one of the safest places in the league to wear an opposing jersey. The most hated player from an opposing team is now lining up at wide receiver for the Cowboys.

Mosely also notes in his blog that "NFC East fans scored higher than any other division." The other 3 were all in the top 10.
