Look around the country, you aren’t going to find very many college football stadiums or outdoor stadiums (with capacities under 30-40,000) hosting non-football events.
You might be able to attract private high school football state championship, but you will be bidding on that hosting spot with a few other cities.
You aren’t going to attract a large artist to play there. Find a band that plays in a less than 40k seat outdoor stadium. There aren’t that many.
You will still have a few marching band competitions, which aren’t exactly money pits
Overall, you’re still looking at 7 (5 football dates, 1 high school band event, and 1 marching band event over the summer) dates, with 1-2 more events, if you’re lucky.
Don’t want to bust y’alls bubble, but people aren’t lining up to schedule events, even with a renovation.
