I think the changes to the revenue distribution allocations within the conference are not of material importance.
The bigger deal is it sure looks like the ACC is agreeing to drastically reduce the impediments to leaving the league after 2030 (by enabling teams to buy out of the grant of rights earlier/cheaper than they could now), ensuring that is what will happen if the SEC/BIG decide they want to take on any of UNC, Clemson, FSU, and/or Virginia (or, less likely, Duke, Ga. Tech, Miami or NC St.) at that time:
"... the total cost to exit the league after the 2029-30 season is expected to drop below $100 million, sources said. The current language would require any school exiting before June 2036 to pay three times the annual distribution -- a figure that would be about $120 million -- plus control of that team's media rights through the conclusion of the grant of rights. This was seen as a critical piece to the settlement, allowing flexibility for ACC schools amid a shifting college football landscape, particularly beyond the 2030 season, when TV deals for the Big Ten (2029-30), Big 12 (2030) and the next iteration of the College Football Playoff (2031) come up for renewal -- a figure Florida State's attorneys valued at more than $500 million over 10 years. Sources told ESPN that there'd just be one number to exit the league, not the combination estimated by FSU of a traditional exit fee and the loss of media from the grant of rights."
