The Navy problems have nothing to do with the team (or their recent travel to a majority Republican state as you speculated last week). Despite the most stringent protocols you can imagine on a college campus, non athletics students and personnel exposed some of the players. The contact tracing associated with that has caused the isolations and cancellations. Where that was invented for the dodge of us, I have no idea.
My sense is that if Navy can’t win the conference and may have possible exposures, then they have operational considerations beyond football, except the Army game. They might be done for the year except that game.
I do think if another team cancels on us, we start talking about demanding third pick in the bowl order if we don’t make the conference champ game
