I realized I already have success scores for each team for the last decade, so I just went and mapped that against the numbers I had at the bottom of the previous post.  

Anyway, Utah and Washington are those twin 32s, both showing up on the PAC12 Network slightly more than you'd expect (given their success), but not markedly so.  Using a linear relationship, here's the teams that show up the most (as compared to their expected value, based on performance)

1. Washington St +9.78
2. Oregon St +7.22
3. Oregon +6.95
4. Colorado +6.18
5. Utah +4.38
6. Washington +4.22
7. Stanford -2.00
8. Arizona St -2.12
9. Cal -4.55
10. Arizona -6.14
11. USC -10.72
12. UCLA -12.33

Mildly surprised to see Oregon and Washington so high on the list.  Oregon had a bunch on P12 Network 7-10 years back and hasn't lately though, so that may be part of it.  Realistically though it just seems to favor California schools... and also apparently Arizona schools.  

Caveat: This is just a quick version that I threw together so there's undoubtedly some factors I'm not considering.  I think (for example) it would be interesting to see who gets relegated to the PAC12 Network most against "better" teams.  And I just tested a linear relationship between appearances and team quality - not sure if that's the right choice, just the simplest place to start.  I'd have to think about it if I was putting together a more concrete analysis. So don't take any of this as gospel, just as more of a first glance
