That's assuming everyone in attendance is actually a fan of one of those teams. People do actually go to pro games to see certain players when they aren't a fan of either team playing. I'd go to a Texans game to see Clowney, but I'm not going to go out and buy Texans gear for it. Honestly, I'd probably wear Gamecock gear as that would stand out more to JDC, if I got a chance to get near him at some point.
Now if I get a chance to see my Redskins this year, DJ will just have to pick me out of the crowd in my Brad Edwards Redskins jersey
