No, I am not kidding. Have you been in the suite levels? Many of those boxes are purchased by internal GT affiliates such as academic schools (mostly for development), other sports (e.g., Golf, for fundraising), GT letterman, etc.
There is corporate demand for more premium seating. BDS is physically limited which is why MBS was considered.
BTW, that remains a trend affecting many other schools, not just Tech.
PS. Fun fact. Many of those premium seats are available on StubHub. The club fee runs about $3,500 a year (some clubs are $1 million plus, per year), plus the ticket. I’ve seen folks who get in for $35. Some club members won’t attend an early season game (too hot) or a crappy game (they travel), so they dump them … or they go unused.
