I honestly think this is the future of stadiums. Less capacity, more luxury, more intimate. If I were Nebraska I would cut about 30k seats out of memorial and spruce it up.
Sounds like that is the preliminary plan for South stadium.
In south stadium I would....
Field level suites
Maybe bottom 1/3rd chair back seating with more leg room
Do a bad ass open concourse with maybe some table seats with servers right before the concourse.
Do seating to a patio at the top that leads to a bar/grill/sportsbook. Have beer tents and all the other shit too.
Then underneath have your museum of Nebraska that you can use to sell tours for. Have the restaurant open year round. Do game day specials for when they are playing away from home.
Plenty of bathrooms too.
