I'm not a jersey guy, but find it funny that it seems ok for grown men to wear them to NFL games, but not to CFB games. Personally, I like wearing a Bama Polo style shirt to games, but I've also been known to pair it with cargo shirts at times, so do I even get a voice?
As far as the worst kinds of fans... Let's start with fans who boo their own team, fans who obnoxiously coach from their seats, fans who sell their tickets to rivals, and fans who have to get up and walk by you on your row a dozen times each half because they need another hotdog and Coke.
