Zero.
If you're going to shut schools out because they don't offer sports, then you can eliminate:
The issue is sports with TV value.
Baylor - gymnastics, swimming, wrestling
Kansas - gymnastics, men's swimming, wrestling, men's tennis
Kansas State - soccer, softball, swimming, wrestling, gymnastics, men's tennis
Missouri - men's tennis
Oklahoma - swimming
Oklahoma State - volleyball, swimming, gymnastics
Texas A&M - wrestling, gymnastics
Texas Tech - swimming, wrestling, gymnastics
And just like that, there are no schools left.
A couple of problems with your argument. One is that the sports in your list do not all have equal TV appeal and value for the TV contract. Do you think that come spring time, men's tennis would have the same TV interest and audience as baseball?
A second problem is that wrestling, gymnastics, and swimming are winter sports, and MBB/WBB are the primary TV draws during the winter. Also, since there is limited participation amongst the schools in wrestling (4), women's gymnastics (3), and swimming (3 men's and 5 women's), would there be significant viewer interest across the network viewing area in these sports? I don't see not having these three sports as a significant detriment from a TV standpoint. Given the Oklahoma schools wrestle, there might be some broader interest for wrestling.
As an example, we might look at what is broadcast on the Big Ten Network. I am assuming they have a decent idea of what appeals to their network viewers. The Big Ten has 7 women's gymnastics teams, and the BTN network this past year broadcast 5 gymnastics meets plus the Big Ten championships. In contrast, The Big Ten network broadcast 30 baseball games, and streamed another 50 on their website. From what I could find, the only men's tennis broadcast on BTN was the championship matches. The BTN did broadcast 15 wrestling matches, but nearly all of the Big Ten schools wrestle, so there would be widespread interest for that sport across the BTN viewing area.
The bottom line is that some sports just aren't that big of a deal as far as the TV network is concerned. If the sports you have aren't on TV or being streamed, then the network doesn't profit from them, and they add no value to the network.

From the TV network standpoint, I see three problems for the Big 9:
ISU not having baseball - missing the primary men's spring TV draw
KSU not having softball and soccer - missing the primary women's spring draw and a women's fall draw (I'm not sure whether soccer or VB is the bigger women's fall draw. Going by what was broadcast on BTN last season, it would appear to be VB, as 19 VB matches were broadcast compared to 9 soccer matches).
OSU not having volleyball - missing a women's fall draw.
