The ACC has a couple of big advantages over the Big 12. First the ACC has its own network that is making a lot of money for both the ACC and ESPN. Second the ACC has several top 20 TV markets. Third the ACC teams are still making more money per team than the Big 12 teams. Fourth, the ACC has Notre Dame and they don’t want the conference to fold.
If and it’s a very big if, a few teams leave the ACC they will be replaced by Big 12 teams. WVU Cincinnati & UCF are easy geographical adds. TCU, TT, KU, KSU, OK St, Arizona & ASU are all good additions to the ACC and the ACCN. It’s not really about the Big 12 versus the ACC, it’s the remaining teams from both conferences simply taking the assets of the better conference.
I think at the end of the day, FSU settles for more performance based payouts from the ACC. Their timing is not good due to the TV providers pulling back. They are not worth a full share in either the B1G or the SEC. They are worth a larger share in the ACC.
I see a lot of problems with your analysis. IMO, FSU is gone and it's only the number we're talking about. In addition, it appears that there really is only a deal until 2027. In addition, there are more rumblings from the so-called "Magnificent Seven" (FSU, Clemson, UNC, NCSt, UVA, VT, UM) to leave also. It appears, the ACC is a "dead conferences walking" . It will never be in the Super Two Conference category. The SEC and the BIG will be paying more than double to their members than the ACC will pay. The recent effort to become the A&PCC by adding 3 geographically disconnected schools evidences more desperation rather then shrewd conference planning.
Months ago I suggested we'll come down to a hard core group of 36-40 CFP schools, most of these are in the Super Two conferences (BIG and SEC) already. I see this as more likely now. Maybe that number jumps to 50 by adding the ACC's "Magnificent Seven", plus ND a couple of one-offs and a couple of current Big 12 members. After that, the pickings get slim.
The remnants of the ACC, including under achievers, BCU,Syra, Pitt, WF etc, will be trying to preserve a conference that is (and will be) weak in football and other than Duke weak in hoops. This is where the rubber meets the road. How valuable in any sport is BCU or Syra to a conference? Let's be real, those schools have been riding coattails to a $30mm payout per year. This especially pissed off FSU and it likewise makes the rest of the "7" pissed off too. I think the TV markets angle is overdone - who in Boston tunes in at any time to watch BCU play football or BB? Even in Boston, college football fans will tune in a great SEC matchup vs. BCU playing anybody. If anything, college sports in Boston is driven by hockey. Getting eyeballs and markets is the end all? That catches up to you when your product doesn't attract viewership...
