I'm sure you know, being from Texas and all: that College fans are infinitely more hardcore than NFL fans, especially Titans fans. No, Those guys would not wear opposing jerseys, because they would be disemboweled. In college, the team aspect is a lot more prevalent, in the NFL, people will spend usually a year or two on a roster, then move along. It's the nature of the league. They're out there to make money, and that's about it. And pepsi and coke are direct competitors, with almost no other competition, the Colts and Titans are branches of the same tree basically. Whole different scenario. NFL coaches get together and have meetings, usually cordially. That never happens in other businesses.
