Like others, I think it would be foolish to expand seating capacity. You're going to need the stadium itself to attract people as much as the product on the field over the decades to come. I would much rather they invest in 'expansion' ideas like additional lounge areas, patio space, etc. Places people can congregate outside of the very cramped concourses.
We had discussed the idea of an upper-deck end zone area, like Texas is doing. Seems like a better way to put money into the stadium.
Or maybe a solar roof that keeps the sound in, like McLane.
The rest of the conference has the whole massive bowl thing, let's do something a little different.
