First off, welcome back Will, or Teddybarexx.

Next, the Rams have been back for 2 years and don't come close to selling out their own building. Why in the world do you think they have a national following?
Second, why are Seattle fans 23? They've been around for 40 years and in 3 Super Bowls
Last, I saw about 75,000 fans wearing logo'd shirts, hats and everything else Sunday, and 90% of them were adults unless they changed the drinking age at the dome.

People in the stands aren't even one percent of all the people who watch football. Doesn't disprove me. Most of my adult friends like sports but don't get silly fan stuff.
I have never been to this site till I signed up..which means that many more people have similar view points that don't agree with yours.
No, jersey sales do not prove the numbers of a fan base. They only prove a trendy purchase. I own stuff from many teams.i like color and design and logo history.
