I'm far from official, but I expect Navy to be all in in American negotiations. AF is definitely "just" an OOC home game in the current CBS/CBSSN contract. Often gets picked up to OTA CBS but not a given. I thought that our ND home games were equally, but have seen some different accounts recently (e.g. Chet's Toner award write-up) that make doubt my certitude.
Army Navy game IS presently its own deal - AAC should now be part of that negotiation -- might be "a la carte" from the overall or within it but a specific line item to up the bidding.
