I love the idea of changing post-season play and removing of unnecessary district games. One option for changing district play would be a change of how teams schedule the regular season, I feel that games should shift towards the men's college regular season format where every region team has to play each other at least once starting in January. You can schedule these games on weeknights, and certain Saturdays throughout the year. On your other Saturdays, you could have events like the Big Ten/ACC challenge or the SEC vs Big XII where teams look for out-of-region opponents who are similar level to them but are not mandatory. If these are hosted where you have 4-6 games in one place, you would limit the amount of resources needed, as well as potentially drawing bigger crowds for these types of events. As far as the region play this would allow for a change in the post-season format where you would be able to seed a regional tournament accurately based on record. If you play everyone once, that gives you 15-18 games and another 15-12 to work with for out-of-region games. You can still have the same format for the Sweet 16 if you so choose, but I feel that this would be the quickest way to allow for a change in the post-season format from a district and region format.
