The only flaw with that logic is ESPN's current investments in the SEC and ACC conferences.
Obviously the SEC is going to get at least 2 Saturday games on ABC each week. And I would expect ESPN's 7p game.
So where does the Big 12 fit compared to the ACC?
I would expect the Big12's premier games would be on Fox and rotate with the ACC in ABC's 3rd Saturday spot.
IMO much of the Big12's value to Disney/ESPN would be:
- Thursday and/or Friday night games.
- Late on Saturday night
- Significant inventory for ESPN+.
- Rotation of top tier games with ACC on ABC&ESPN.
Game slots by Network are contractual, so it's not really a "step" process.
