For games on ACC Network or RSN, Raycom pays ESPN for the right to show the game which they distribute to local stations or regional sports networks around the country. In return the game is blacked out on the ESPN app in the areas they are showing the game. I believe you might be able to steam this afternoon's game on the ACC website though.
It airs on the following stations in Florida:
Florida Fort Myers-Naples WXCW CW
Florida Gainesville WCJB ABC
Florida Jacksonville WJXT IND
