Can't believe this thread won't die. As for me, I get it - the rules are, you can stand the whole time. You can also fart in a crowded elevator all you want. You have that right, and nobody should take that away from you.
I too stand at games. I stand when - it's a big play about to happen, touchdown, team enters field, fight over in section K, Spurrier throws visor, cheerleader wardrobe malfunction.
I also stand when the guy in front of me stands. Which means the people behind me all the way to the top have to stand.
OK, so some common sense and consideration should prevail. By my standards, and flame me if you want, I don't care.. when tall guy and his buddy are standing during the "Play under review" thing, and we are trying to see the jumbotron - at that point, there is no reason to be standing just for the hell of standing. Not everyone is 30 in the stadium. Lots of folks got to Knoxville hours before kickoff, stood for the VOL walk, parked downtown - walked miles and miles.
Stand if you must, but don't be surprised if someone asks you to please sit down for a while. I've done it.
