I always figured they'd expand more behind the basket opposite the student section, where the main concourse is. You could expand that whole section upward into where the offices currently are - turn that office space into luxury boxes, and expand more seats to fill that baseline area much more than it already is. Blow out that side of the building to have a larger concourse area, food court, merch/apparel shop, etc.
I'm a season ticket holder in the 300s, and I have no need of seat-backs up there. I'm not opposed to having the ring around the court be students, though.
