I sat a few rows behind the Tennessee band. They were annoying, but in the usual pep band way, nothing particularly about us. The fans near us were very cool. Interestingly, none of them still live in Tennessee! I was able to take a video of one of them on jumbotron and airplay it to him. He was super grateful and said his grandkids wil love it.
Perhaps the most heated interactions I saw were started by Charlie Kolar (backed up by Jake Hummel, Mike Rose, and other former football players) in the concourse trash-talking a group of Tennesseee fans. One woman in orange and white came up to Charlie and looked at him right in the chin and gave him the business. It was really fun. I don't think they knew that they were dealing with an NFL player who is also really smart and good at competitive banter. He held his own with a whole group of Tenn fans.
