I used to think that if the B1G or SEC expanded to 16 (or beyond), it would make them play each other more, and have less patsies. Now, I'm not so sure that is the case. Nothing would really keep them from playing the same number of noncon games, yes or no? Their media partners do come to mind. I suppose if their media partners wanted to see more of them playing each other (vs patsies) it would happen. And sure, some of those noncon games are not patsies. For example, Ohio State scheduling Notre Dame, etc.
But unless they get a strong nudge, does anything change? Will the SEC still be allowed to schedule 4 noncon games and only 8 conference games? Unless forced otherwise, I think they will try to continue as is? Will the B1G and SEC (and eventually Big 12?), be asked by their media partners, to increase their conference game schedule to 10, rather than 9 games (or 8 games, SEC)?
Edit: With the amount of money involved, the media partners will likely have a strong say in the conference scheduling, and the number of noncon games?
