Oklahoma's defense did well against Tech, Cincy, and TCU, but all those games were in Norman. They seem to have a Jekyl and Hyde thing going with their defense depending on where they are playing.
Also, you said "So this does bode well for OU if they continue to be disrespected.", implying they have been disrespected all season or something. Yeah, they won the BCS tiebreaker, and they're #1 in the country. They are really disrespected, man.
