I'd bet the cheapest seats at the top of the endzones are the hardest to get not the lower bowl endzone seats. It's easy enough to jump up in the order by joining the CC at even the lowest level.
Also, why should BYU be more concerned with bandwagon new fans over fans that have been buying tickets for 40 yrs? These new fans you're so concerned with are just as likely to stop buying just as fast.
