If the average attendance for students is 12,000--let that be the magic number and open up the rest to TP waiting list.
rgw, I totally DISAGREE that the games are about the students in the stands and have nothing to do with alumni/boosters/fans in attendance. The people who pay to own sky boxes and by Tide Pride memberships and tickets have just as much "claim" to a game as those who attend school there. I would venture to say that I and others, as alumni of the University actually have MORE ownership because we already paid complete tuition to go there and if I wasn't on the waiting list, would be paying exponentially MORE for my tickets. Therefore, my financial investment in the University is much greater than that of a student!
The games are about the players and the coaching staff. Put as many people in that stadium as capacity allows who are there to CHEER on this team! If you are there to make it simply a social event--stay on the Quad or the Strip and look cute!! Otherwise, GET out of my way into that stadium! I am ready to cheer and cheer LOUD for my alma mater!
