Take another look at the article. These numbers don't purport to be the value of the schools to the B1G but rather that value added to the BTN. Even for that it is hardly definitive, more of a back of the envelope estimation. For example Patrick, the guest who made the chart says
"Regardless, at $0.36 per month for 26,000,000 households over 12 months I only came up with $112,320,000 for a cable carry rate. Well short of the $272,000,000 that the network likely made last year." He assumes the difference is advertising. That's what known as a "plug" which is an assumption to make the math work.
There isn't a lot back up but I would be curious to know how he developed his "households" number. I suspect that the he used the Hartford/New Haven DMA numbers solely, which as we know excludes Fairfield County and parts of the eastern part of the state. ...Yep I took a look at his back up chart and he shows 1,010,000 household in Connecticut. The actual number is
1,360,184. He also assume a flat per home increase in revenue. Stated differently, he assumes the value watching a college game is the same everywhere. So Boston college brings 100% of viewers in it's DMA. We know that's not true. SNY's investment in Connecticut basketball is a great indicator of the depth of interest in Connecticut. Not only did SNY, after years of failing to draw interest, suddenly get 100% penetration in Connecticut, they did so charging a premium for it to be on the basic tier. That isn't reflected in his table.
Keep in mind also that every household isn't fungible in terms of advertising value. Connecticut is one of the highest (it's usually us or Jersey) household incomes in the country. Reaching those homes has more value to advertisers than, say, upstate New York.
Finally Connecticut has enormous name recognition (call it a Q rating...sort of) for basketball. Not many people are going to tune in across the country to watch a BCU game but they will to watch the national champions. That's not reflected in his chart. For what it's worth, while woman's basketball certainly "doesn't drive the bus" in conference realignment, UConn Woman's basketball bring value to the BTN by generating product that people actually watch.
Stuff looks pretty official when organized into a chart, but I suspect the B1G has done a significantly more in depth analysis.
