I've waited almost a week to repost my hunch, but I'm thinking John Angelos works a deal to get an expansion franchise in Nashville and gives up his ownership rights in the Os to MLB. The Os become a ward of MLB, like the Nats in 2003-06 and are sold to a new group that keeps them in Baltimore. MLB would release the Nats broadcast rights to the Nats or sell MASN to Leonsis.
That seems like a decent hunch, but an expansion team in Nashville with John Angelos in charge seems really aggressive for where MLB to Nashville stands right now. The "group" pushing for it locally has been very loud in their desire to be the first black-owned MLB team (aka they are forcing any potential owners to include them) and an Angelos kid bringing a team here is a surefire way to start with complete apathy. Plus, the state and city are paying for a new Titans stadium and I'm not sure Angelos has the money, desire or interest in self-funding a stadium in the suburbs. The Titans stadium has been a super hot issue and there's not really a good place downtown for a stadium, though this is probably a Cobb County-type situation for MLB anyways if you know what I mean.
Also does Manfred have the energy, ability or interest in working out a deal like this? He is lazy, unimaginative and disinterested in actually doing commissioner-type work.
