While correct on the 5/5 for the ABC/ESPN/2 argument I think another possible flaw was another station just as "national" as ESPN/2. I went ahead and listed FX as I've come to find it is on my basic package of DirecTV and is in 99-100 million homes like ESPN/2...and therefore every bit as national. FSN - not so much - while I and many other satellite users could get them - it requires a higher cost sports pack and likely does not have any of the individual regional's permeate above 40 million homes...
Texas
3 - ABC = OU/OKSt/Baylor
1 - ESPN = A&M
1 - ESPN2 = BYU
1 - FX = Iowa St
Oklahoma
4 - ABC = FSU/TX/TxTech/OKSt
1 - ESPN = Kansas
3 - FX = Tulsa/MO/Iowa St
There are still 3 weeks not decided yet by the broadcasters that could add to those totals so far.
Texas = vs TxTech, @MO, vs KSU
OU = @KSU, vs A&M, @Baylor
