I can't speak to how we will be able to buy tickets and whether or not a season ticket option will be available because I don't know. What I do know is that it will be going to a priority points system where students who have the most points will have priority on seats. The less hyped games (WKU, Ohio, etc..) will be worth more points than the more sought after tickets for games like Georgia. I'm sure SGA is still working out the final details of the system.
Also, the reason it keeps changing is that whenever the Athletic Dept. decided to start charging students for tickets, SGA and the Assoc. Dean of Students knew it would be a trial and error process. So this change is an attempt at a better system after a lot of students were unhappy with the way tickets were distributed last season, myself included.
