From a different thread....
the bold italics is added to address your original question.
So, let's just play this out - if it remains just USC and UCLA, which would make 16 teams (and I know there will be more, but just play this out).....
and the limit is 12 regular season games.
4 divisions
East - Penn State, Rutgers, Maryland.....Michigan State (because it means not facing OSU every year).
Mideast - Ohio State, Michigan, Indiana, Purdue
Midwest - Northwestern, Minnesota, Illinois, Wisconsin
West -Iowa, Nebraska, USC, UCLA
3 games vs. your division 2 from each of the other 3 divisions (Home and away), Total of 9 Conference games. Leaving 3 games. Assume two G5 or whatever the hell is left over - so now a total of 11 games.
Best teams from each division play each other so there is 12 regular season games for the winners of each division. The other 12 teams play each other on the 12th week, similar to what the conference did for the 2020 Covid Year. So now all teams play 12 games. And you have 10 conference games.
The BIG can ensure that teams will get 5 home conf games every year, regardless of whether they win the division or not. So, in a year when you play one division opponent at home (and two away), then you get the six division opponents split 3 and 3, you would get the 12th week opponent at home. In the other year, you have the extra division game at home, you are the away team on the 12th week.
Then it's up to the individual schools to schedule non conf games so they can enjoy an extra home game, if they need it that way. Of course, that would probably mean that all the good intesectional matchups are gone. But, you are getting 10 conference games. The issue of the extra home game is not really the conference's issue, it's an issue for each school to resolve.
After the 12th week, the two winners of the four division winners meet in the CCG (which may now have to be in LA). So, that is the 13th game. The winner can go to the approrpaite bowl/playoff.
Logisitics is probably the biggest problem - teams have to move equipment and personnel around, but that can be managed. So, for instance, every other year, PSU knows it's travelling for an away game, but they just don't know where. Could be Iowa, could be Minnesota, could be USC.
Edit - to ensure this, certain season ending games would have to move up a week to the 11th wek of the season - OSU/Michigan, the Lincoln Hat game, the Old Oaken Bucket Game, the Axe game, the Iowa/Nebraska Game and the Mayor's Cup between USC and UCLA.
