The ACC (not the SEC) did work out a deal with the CW to carry the third tier of ACC football games that aren't on a Disney (ABC/ESPN) network. This replaces the regional sports network (Fox/Sinclair/Bally) agreement that the ACC had prior. AFAIK the SEC doesn't have anything similar.
When the ACC struck their most recent agreement with the Mouse, there was a carveout for the third-tier games for Raycom, which had carried ACC games in syndication for decades. Raycom was also headed by the son of ACC commish John Swofford, which I am sure had nothing to do with anything. People have commented that the ACC-ESPN deal could have been a lot more beneficial for the ACC financially had this carveout not been insisted upon.
More recently, ATL-based Gray TV bought Raycom, and Gray also owns a lot of CW affiliates. When CBS and Warners sold off most of the CW, they also pulled affiliate agreements from their O&Os like WUPA in ATL. Gray (who had bought Peachtree TV WPCH Channel 17 from Meredith when Meredith got out of broadcasting; Meredith had bought Channel 17 from Time Warner) then affiliated Peachtree TV with the CW.
