SIAP.....
The last couple of seasons the University has offered the "Vol Pass" for basketball. Its essentially a season ticket but you don't have the same seat every week. A few days before the game, you get an email and you jump on the site and select your seat(s). Obviously the best seats go first so the quicker you get on line the better your seats.
Anyway, the University is offering the Vol Pass for football. $280/ticket for the season is pretty dang good with no donation required.
