What you are missing is that the Big 12 football TV ratings are blowing away the ACC and that will have an impact when the next media contracts are negotiated. And, the ACC is more likely to lose their top schools (Clemson, FSU, North Carolina) than the Big 12. Here are the top 3 rated games for each conference over the past 3 weeks:
Week 13:
Big 12: 6.22 million, 1.91 million, 1.31 million total = 9.44 million
ACC: 0.985 million, 0.897 million, 0.262 million total = 2.14 million
Week 12:
Big 12: 4.00 million, 1.75 million, 1.00 million total = 6.75 million
ACC: 1.85 million, 0.957 million, 0.298 million total = 3.105 million
Week 11:
Big 12: 3.68 million, 2.07 million, 0.378 million total = 6.128 million
ACC: 3.46 million, 1.44 million, no 3rd game rated total = 4.90 million
And, according to the Sagarins, the Big 12 is the #2 football conference and the ACC is #4.
