That is a well kept SU secret but making some assumptions and doing some math
I'd say it is safe to say it would easily be approaching the mid thirties (this includes the students and plus add in any unknown corporate buys too). It would also be safe to say averaging 42K a game is a given and depending how the season plays out it could be 2-3K higher. Having WMU and Holy Cross on the schedule will hurt overall attendance. The Wake Forest game will also hurt (Thanksgiving weekend--few students). Unless we are undefeated, I figure walk up sales will be down a bit, many of those walk ups bought season's this year. Another thing that hurts is Clemson is the only school that travels. We have the holy trinity of travel support suckage (BC, WF and Pitt) on the schedule. I'm kinda serious, Holy Cross will probably travel more than these schlubs. I'm still thinking 42-44K range for season average is the range.
1998 was our high point and for years we have said it was 38,000 season tickets in threads on this board. (I believe Bee's mentioned 38K years ago from a source in the know.) I think it is safe to assume we should be able to hit 34-35,000 this year when students and corporate are added.
