The ACC is more stable than the Big 12 and Pac 12, and the money will move up. Only some of what was discussed in Amelia Island has been reported, as most discussions and fact-finding are on going. The ACC is working on some new avenues with "loopholes" in the ESPN deal that could allow for increased revenue, notably allowing schools more control of ACC Network advertising, streaming, etc.
The seven schools dubbed the "magnificent Seven," which was a term assigned by someone in the media, which annoyed the ADs and was inaccurate, are in complete alliance with one another. They ALL recognize that their strength together is best for everyone longterm in all facets: Competition, control, and money.
There is so much going on behind the scenes right now. Allow this time to play out. The league has some smart and shrewed ADs (guikding the presidents) that have already begun moving things in the right direction with the psotseason revenue decision.
