The defense was trapped in a never-ending Groundhog's Day of fresh downs gifted to Oklahoma with dumb penalties, mental letdowns, and an initial inability to deal with tempo.
OU should have been stopped cold on three of their scoring drives, but we (or occasionally the imaginative refs) offered a generous TARP bailout whenever they experienced four down liquidity issues. This was a theme throughout the game and you can't win with our offense when your defense gives the opponent's offense a bonus down every ten.
