Actually, I think those won't be going anywhere. You have to remember, like football, all these programs will still be looking to get their "requisite" number of home games in (i.e. revenue).
For example, Iowa only played 31 regular season games last year. A 24-game conference schedule probably means 12 and 12 home/away. That leaves 7-ish games for OOC. Iowa played 17 home games in the 2022-2023 season and 7 of those in the non-conference.......
So with the new schedule, unless Iowa wants to give up home games for SOS, you'll be looking at about 5-6 home games still and only 2, maybe 3 road games or early season tourneys, and one of those road games will be Iowa State every other year.
