I'll give you two potential conventional bidders: CBS and AT&T Warner Media.
CBS has already been broadcasting AAC football and basketball games and this is where Aresco came from. And, CBS Sports Network needs more content with the future of unbundling. On the CBS network, CBS has some SEC football game rights, mostly 3:30 PM games. They have noon and night time slots mostly open. And CBS already does the Army/Navy game and the ND/Navy games when Navy is the home team. CBS already owns the NCAA basketball tournament with Turner Sports. And, CBS has a hole in their weekend lineups in the winter and could use some weekend day time basketball games.
As for Turner Sports, they own TBS, TNT, and TruTV and they own part of the NCAA men's basketball tournament with CBS. AT&T just bought Time Warner and they have deep pockets and a larger market cap than Disney. Turner desperately needs more sports content to remain relevant and they have financial risk with unbundling.
Finally, the big streaming services are all bigger companies that Disney by market cap: Alphabet (Google): $780 billion, Amazon: $825 billion, Facebook: $563 billion, Netflix: $170 billion, Disney: $155 billion. Do they find college sports an interesting asset to expand? Remember when the Big East signed with a young company named ESPN back in the day? It was groundbreaking. Would they start with the AAC and then go after other conferences later?
