An SEC that has the Texlahoma 4, Clemson, Florida St, and 4 more choice ACC schools controls more than half of the college football market and as such could probably distribute $50 million per school.

The Big 12 and ACC would roughly be on par with the old Big East in terms of value.
You then have the Pac 12, who has limited value and can't field content in the 12:00 eastern time slot. Better than the other two sure but still miles behind the Big Ten.
Then you have the Big Ten and with the new content you've grabbed you're still way ahead of them.

The south, college football's most passionate geographic region, is solidly in your control. In most of those states you either are the only show in town or vastly more popular than the other options in the state
