I'd wager to bet that as the season goes on, the capacity increases. There are some good trends going on with the case numbers. December a long way off yet.
Only problem is that season ticket holders need to understand what to do by the first game. Getting the refund in September doesn't help you in December.
If many take this option, it might mean folks like me, who are absolutely going to go to as many as allowed, will have more games to see.
Just heard that Bama is 20% for the season. Seems a little nuts to lock that figure in stone at this stage.
