Super vague indeed.
Cal, Stanford, and especially SMU giving up money to join buys time for the rest of the league. Part of that time will be used to get everyone to agree that a portion of the TV revenue must be distributed to those schools that draw the most TV viewers. Wake and BC certainly will always oppose that, but even for them, it is better to do that than to have the most valuable 4 -6 or even 8 members leave.
So how does a school like Syracuse guarantee it draws TV audiences that are larger than those it has been drawing (other than having back to 10-2 teams)? Improve OOC scheduling, with a focus on large student body state school foes. Cincy, UCF, USF are all that, and also are located in areas with huge numbers of recruits. Even FAU has 30K students. Temple certainly is large.
