If we really want a bigger looking stadium with a reduced capacity (see JMU), make it nicer, not just bigger.
Full green chairbacks (except student section)
It reduces capacity, and you can add deck/suites, loge, to other side. And end zone.
Add restaurant, brewery,(both open year round with stadium views) and a beer garden.
Have better concourse, restrooms, concessions.
TVs everywhere.
That's how you do it. Quality over quantity.
Make it a hard ticket to get.
