One point of contention I have with the "ACC will survive...in some form" sentiment is...well, that depends on the media. More specifically, it depends on whether the media wants to enter into a BILLION $$$ plus contract with the ACC "leftovers".
FSU leaving at some point is an all but foregone conclusion. North Carolina has signaled they need to leave the ACC to compete with their "peers" if the ACC doesn't improve its financial situation (it won't). UVA will follow UNC wherever they end up as they've been a high priority for the B1G and SEC for decades now. NC State is politically tied to UNC, which probably means NC State goes where UNC goes. Even if UNC's next conference isn't willing to take NC State, UNC has enough clout to move alone. Miami is highly valued by the B1G for the South Florida market/territory.
FSU-UNC-UVA, IMO, are all but certain to leave when the window opens. I tend to think Miami will be gone as well, but I don't feel as strongly about Miami as I do the other 3. Those schools leaving drastically reduces the value of the ACC. Now you get into a situation where the Big 12 looks awfully good to some of the remaining ACC members, and some of the ACC members look awfully good to the Big 12. Specifically, VA Tech/Pitt/NC State/Louisville/BC/Syracuse/Duke...and GT, but more on us later. Doesn't mean they all go to the Big 12, but some of those schools would be attractive to what the Big 12 is doing. New territories, equivalent fanbases, and the Big 12 is quietly building a college basketball equivalent to SEC football.
We're basically looking at the same scenario that dissolved the PAC 12. The "big brands" leave, the value of the conference gets reduced drastically, the remaining "attractive" schools leave for a better financial and administrative situation. IMO, there are 4-6 ACC schools that end up in the SEC and B1G. The rest will get picked off by the Big 12. Even with the addition of Stanford/Cal/SMU, that doesn't leave much for the ACC. It certainly gets worse for the ACC if we have to backfill with G5 teams. ACC will not be backfilling with SEC/B1G/Big 12 teams.
Back to GT. All my research, which I won't repeat but you can look up in this thread, leads me to believe GT is more likely than not going to end up in the B1G. The growth of Georgia (currently 8th most populous, and soon to be 6th or 7th within the next 5-10 years), the economic powerhouse Georgia is becoming one of the top business markets, and high concentration of B1G grads is too attractive for the B1G to pass up. You can help grow a school's fanbase, but you can not grow a market/population center the size of Georgia. Also, a good percentage of the B1G's markets are currently going through negative or flat growth, which means the B1G needs to expand into territories that are growing. Georgia (GT) and Florida (FSU/Miami) are EXPLODING. Fanbase size is important, but so is the source that grows fans of schools. Right now, the "source" of B1G fanbases is in a flat to negative growth trend. Expansion is a 50+ year decision. There's a reason why Kevin Warren's expansion plan (former B1G commissioner) was modeled after states with NFL franchises. The NFL doesn't move to cities without a big economic and population base.
Worst case scenario for GT is we end up in the Big 12 if the ACC falls apart. The SEC does not need GT with UGA in the conference. We'll see, but I think GT is in a much better situation than some GT fans think.
What media company signs up for the ACC "leftovers"? Certainly nowhere near the price of what the ACC got with today's membership. It's more likely the ACC dissolves much the same way the PAC 12 did than gets "saved". Members getting picked off to the point the conference no longer becomes attractive to anyone. You have to be blind to not see that media companies are consolidating operations...which means they will find more reasons to NOT keep the ACC alive than to pump money into the ACC to keep it going. I'll go one further and say ESPN and FOX are probably pushing behind the scenes for some of the ACC schools to move to other conferences so they can wrap up their conference tie ins and save hundreds of millions in cost. It's basically what they did with USC and UCLA (and eventually Oregon/Washington) going to the B1G, and the PAC 12 schools that went to the Big 12. Funny how all of a sudden FOX and ESPN (as well as Warner Bros) now all have an agreement to consolidate their sports channels into one mega sports streaming option. If you think the ACC is in trouble, wait until the media contracts for the G5 conferences come up for renewal.
