This is what I have been saying along that the platform and the time is more important than the teams, unless you are one of the 6-8 blueblood programs like Alabama, Ohio State and Michigan.
If CBS takes Kentucy vs Missouri and puts it on as their primetime Saturday night game, it's going to get decent ratings, take that same game and put it on the SEC network and the ratings drop to half. Now why, the teams are the same, but the difference is you lose the casual fan and now only have the hard-core fan that wants to watch his team or his league play. ISU or EIU will draw a decent rating for an ABC or ESPN prime time game also but put them on FS1 and the number drops.
When Bowlsby said the OU and UT were worth half the leagues money, that is because they were the teams that were always getting the prime-time slots, therefore they drew the biggest ratings. If UT was such a rating drawer, why did no one watch their games on LHN. Because when on that network, only the true hardcore UT fans tuned in. The casual viewer found another game to watch.
Stewart Mandel and Jon Wilner have a bias and vested interest in the Pac 12 surviving, so they are going to push numbers that support the belief that the Pac 12 conference is more valuable than the B12 conference.
