When OSU plays UTexas, it has to be great benefit to OU for me to not pull for the Pokes. I know the jealousy spawned hate is pretty strong from most of the other side, but that doesn't matter to me.
I can't think of any non conference game when I wouldn't hope for an OSU win. Very few nc games when I wouldn't pull for the Pokes.
When the Horns venture out of the conference, I usually root for their opponents.
