It sounds possible, but here's what they'd say about that game when it comes time to workout the playoff spots:
1) That was early on in the season, if Oklahoma played them now, it would be different
2) Player X (no matter how insignificant in reality) was the key to Oklahoma and he was suspended/injured/not playing well that game.
There are no computer models, there is no objective data... there are 13 people, in a closed room, who all represent P5 schools and conferences. Not formally, active ADs, whose budgets are tied to their conferences making the playoffs and big bowl games.
This is not the 1980s... even the great bobby bowden couldn't "climb the ladder" in this day in age. CFB is big business and those with a seat at the table don't care to share more than a crumb (access bowl slot)
