Expansion should be so easy - do away with first four, and have x amount of at larges have one game playoffs with the winner getting into the bracket. Maybe rank the last 6 in and the first 6 out, and have the last 6 in host.
This is almost exactly what she was describing, but moving the first four exclusively out of Dayton and having one game in each of the time zones so the teams who make it through can stay there and don’t have to fly out of Dayton immediately to somewhere across the country.
She also said they can’t expand too much because the media partners won’t let them anyway (hard stops because of other sports commitments).
