Don't think so. I don't see the SEC adding Clemson, FL St, VA, or NC. The SEC is already the top conference. This is about big network money, pure and simple. Why split up the money that many more ways when none of those schools would pull their own weight by adding significant media markets? Makes no sense, so there would be a lot of opposition from current members.The SEC is going to be a college version of the NFL. It will be so competitive the days of going undefeated are going to be exception not the rule. The portal and NIL will make it harder and harder to build depth.
With the playoff 3 losses in SEC may still be viable. Any team can get you at any point.
Then the potential of adding a FSU and Clemson to the SEC good freakin luck. If I was SEC I add Virginia and UNC. Two markets you don’t have with OK football brands. The SEC doesn’t need more powerful programs.
In addition to that, UF would fight against bringing in FL St for territorial reasons and I wouldn't blame them. For same reason, SC and GA would not be happy with Clemson. I don't think SC would like NC either. Lot of complicated territorial politics there over little or no financial benefit.
If feasible, the SEC should add ND (Chicago), Univ. of Miami, and Univ. of Houston, three huge media markets that would bring in very big money. TCU could be attractive because of the Dallas Ft. Worth market. Could also consider UCF (Orlando market) but UF might not go along with that and I wouldn't blame them.
