You are terrible at reading comprehension.
Let's take it to the extremes to make a point that is so elementary it shouldn't have to be explained. If a show on cable has zero viewers, ad value for that show is worthless. If a show gets 20M viewers its ad value is much greater. Maybe you didn't realize it, but ad value for the Super Bowl is much greater than a rerun of Survivor on the same channel at the same time.
Cable gets ad value, but that value is dependent on whether or not people watch. So again, every factor keeps shifting value toward actual viewership, and away from being a team that lacks interest but lands a bunch of carriage fees. That doesn't mean the latter is gone and is not important, it is just shrinking as a percent of the overall team value vs. factors that require viewership.
The point is it's not "streaming" vs. "cable/sat." It's factors of value that require viewership vs. those that don't. The big ten had a model that could capitalize on the latter very well. It still does, but that has and continues to be of reduced emphasis. However, the Big 10 is still in good shape because OSU, Michigan, PSU and Wisconsin get huge viewership on the over the air networks, which of course is ad dependent. So Big 10 is still going to get a lot of money, it's just pushing the value of the conference even more toward those four and away from the Rutgers and Marylands of the conference.
