It won't be the ACC, per say. This is after it dissolves, falters, breaks apart, ends, or whatever happens.
The bold is the plan. It's a group of the schools that are aware that they're being left out or contingency planning. It's something administrators at Duke have pondered for years apparently. Miami is included in talks as a contingency for themselves.
Miami desperately needs FSU and/or Clemson to pick the SEC or be picked by the SEC. If they both do, we might be out in 2025/2026 and part, maybe even all, will be paid for.
Of course Vanderbilt, Northwestern, etc. won't leave their conferences. But they're not going to be included when ESPN/FOX says they want the top 40 teams, 2 conferences, and the rest aren't being written into their rights and are kicked from the conference. That's where it's headed.
