Since you hinted that Baylor should be favored @ Oklahoma I got curious and went back and looked when the last time the Sooners were a dog at home. Turns out it was 14 years ago against Nebraska. This is actually the shortest that Okla has been favored at home since 2001, when they were -4.5 against Kansas State. I don't know if that speak to how well Okla has been at home, how weak the Big12 conference has been, or their out of conference scheduling.
