If we win out, we would give Oklahoma a loss, and Oklahoma also still plays both Baylor and Oklahoma State. Every other team already has two losses.
If Oklahoma beats both of them, then there would only be two 8-1 teams. We are in vs. OU.
If Oklahoma beats one of them and loses to the other, then once again, only two 8-1 teams (us and whoever beat OU, since both OU and the team they beat would have two losses). We are in vs. the other winner over OU.
If Oklahoma loses to both of them, that's the only scenario in which three teams can go 8-1, and we already did the math on that. Baylor would get eliminated on points differential. We are in vs. OSU.
So there is no scenario we are out if we win out. We control our CCG destiny.
