found another excerpt from the New York Post article by Andrew Marchand, dealing with Apple TV's role in the negotiations.
"For the Pac-12 to reach the $300 million per year mark to basically match the deal the Big 12 received from ESPN and Fox Sports, the most likely platform to pay that at this point would be Apple, as we reported last month,” Andrew Marchand writes. “To be clear, we aren’t saying that is happening, but Apple is the company that could potentially reach that number, and adding Pac-12 rights does fit what Apple seemingly is trying to do in sports. But it figures to be an all-Apple deal.“
to be clear - an "all-Apple" deal would mean all of the Pac-12 games would be shown on a streaming platform.
so, from a dollar-to-dollar comparison, the Pac-12 could theoretically reach the $30-million per team mark - but from an exposure viewpoint, it's hard to compare an all-streaming deal to other conferences that will be on major networks and/or ESPN.
If Marchand is correct (certainly a big IF) then the Pac-12 could be facing a choice between more money for a streaming deal, or less money to be on ESPN.
