My guess would be WVU v Baylor for the Prime Time game. What you are missing is that all the P5 conference TV contracts require a certain number of prime time games, so ABC will put weaker games in the 8 EST slot to ensure they give that conference the number of prime time games the contract requires.

We will see BYU games get better time slots, just probably not the ABC prime time slot; instead we'll get the ESPN 7:00 EST slot or afternoon slots. If Baylor can remain undefeated until we play them, that would likely get the prime slot — but it is unlikely as Baylor has Iowa State, Ok State, and WVU in consecutive weeks before that game. Also, there is likely a good chance of BYU at USC getting a prime slot, either on Fox or ABC, assuming both teams are still ranked.
