The money is one aspect of it, but exposure is another and it's not a non-issue when it comes to streaming. Simply saying, "Apple is a massive company that knows how to market, therefore we'll have plenty of exposure, etc, etc" is nothing more than wishful thinking. CFB, and more specifically, Pac 12 CFB is not a material product like an iPhone. It doesn't appeal to everyone, and it's not Apple's proprietary product they can fix themselves and capture a massive market. All the marketing $$$$ in the world isn't getting east coasters to tune in for an Oregon vs Arizona football game.
Again, what does logic tell you is going to happen to the ratings of the Michigan State vs Washington game that was put on Peacock in early September? Will those ratings be better or worse than if the game was broadcast on NBC, ABC, CBS, FOX or ESPN?
