My guess is the relevant programs in G5 have some deep pockets in the background calling shots. When they call the AD, he answers immediately. Maybe at times he doesn't do exactly what they ask, but he listens. Those luxo-boxes ain't cheap.
I was invited to one at a Reds game back in the day, well the wife was and I tagged along. Few paid ANY attention to the game, it was a schmooze fest. There were some kids and moms who sat in the seats watching a bit, most of the men stood around chatting, maybe they'd look out when the crowd made noise.
I found a corner and hid. They had a dude mixing top shelf drinks and some serious horse's douvers. The wife had to schmooze a bit, she'd look over at me and smile, crookedly, and told me later I should have schmoozed a bit, the head of GEAE was there and I had met him once before.
I didn't see a point. And that was MLB, it gave some insight, perhaps, into those luxo boxes at Ole Miss games.
They built MB stadium here for $1.5 billion, and the Georgia Dome was less than 30 years old and still in good shape, but not enough luxos.
