We've sold 32k season tickets, down from 35k sold at this time last year.
You've sold 32k season tickets and are sold out.
We would have to sell 6k more tickets to sell out.
If we were holding 11k for students like you guys are, we'd only need to sell 2k more tickets to sell out. Either way, we've both sold around 32k tickets this year.
As to OP4's question about the difference...some of it is visitor tickets, but evidently both schools hold back some tickets for individual ticket sales. You also have to considered that some tickets are held for employees, recruits, other visitors, etc.
If our capacity is 60,850, we evidently keep around 8,850 for visitors and individual tickets sales. If your capacity is 55,082, then evidently you hold back 12,082 tickets for visitors and individual tickets sales.
