The thing here though is the over the air depends mainly on the amount of inventory you have. The more you have, the more good stuff you can put on linear for a higher return and you dump the garbage on streaming/conference networks for some extra loot.
The B1G, at 14, usually puts 50% of its 63 games on linear, but they're massive games, so they drive big numbers. The rest funds the BTN carriage because all those fans want to see those games.
The Big12, at ten teams, had nearly 75% of their 45 games on linear, because they didn't have enough to find a network/streaming and it was the only way to maintain the same level of competitive revenue. You'll see this get distorted in twitter viewership analysis, because all the stuff that would end up on a conference network, which isn't metered, was now on FS1, which is, so they have a lot of low interest games that most conferences bury in the not-metered market. If you ever wonder how the B12 survived losing Texas and Oklahoma, its because they drew really well in these games everyone figured would go unwatched.
The Pac currently only has ten teams, but also has an anchor of the Pac 12 networks, with an agreement of 2 football games per year. This means that, unless they fold the PACN, which would be a massive loss write off, the Pac only has about 25 football games they can even take to market, any market, linear or streaming. Even if they could sell all of those, its still less than what the B12 sold to get their current number.
The only thing I can think of that is "creative and forward thinking" that can save the PAC's ass at this point, is...
Sell the entirety of the PACN to Apple for around $100m, which pays off the Pac's current issues and gives Apple a linear footprint in 14m west coast homes
Apple gives the Pac a $3b deal over ten years for the rights to all of their content to be used in any way Apple wants, but most games are now Linear, just on this new channel.
Apple rebrands and begins to fill the network off sports, featuring their shows on linear before they move to streaming, increasing buzz and viewership
Apple expands its footprint organically by providing local MLB (who is losing local rights in many markets with RSN melt down) and MLS games, in market only (the NFL model) the US in sports markets - double win when the there is both a baseball and soccer team. Each expansion increases size and carriage.
Become a player in future local rights, including the NBA
That saves the Pac with a $30m/year deal, in PR at least as they won't hit that $30m/year average until 2030.
