With only getting 3 games per year, I do wonder. I can see them wanting to have the B1G game as a lead in to a 7:30/8:00 kickoff. I was looking at future schedules and this and this was an example of it:
Notre Dame at Michigan State - 3:30 | CBS on 9/18/2027
Washington at Washington State - 7:30 | CBS on 9/18/2027
I'm assuming they are going to put some of these bigger OOC games on CBS, but don't think they'll want to put them on at 10:30 ET. For example for 2027 if you assume CBS will air Missouri/SDSU and UW/Wazzu that leaves just one game left. I do think we'll see a lot of games on CBSSN #afterdark.
I am interested to see the other media partners.
