I notice this list has NFL.com team logos, so I will assume that this is their bullshit product.
I guess if you're not buying officially licensed NFL apparel (available at
www.nflshop.com!!!), then you're not a fan. I interpret this as (for the most part) the more loyal fans are at the bottom because they've had gear for years and don't jump from one team to the next on a whim.
Or maybe NFL.com has some ****ing moronic magic formula that discovered the two biggest dickweed fanbases in the league are the most "loyal".
