Perhaps ideally the Big 12 stays at 10, along with the Big 10 staying at 12 and the SEC at 14. In reality, the SEC and Big 10 are moving towards 16, and the Big 12 will need to as well.
1.) The Big 12 needs to move from the araciac view of TV as a contract and get onboard with cutting out the middle-man and viewing it as a tax. We need the population that comes with 16 (or 18 with the two conference semi-final games).
2.)In the likely play-off system, a conference of 12 teams is at a handicap if others are at 16.
Inviting UL may be needed to further open up the ACC. If not, then great.
