Oklahoma was announced as the nation's new No. 1 team Monday afternoon at 1:31 ET.
The top-ranked Sooners lost roughly nine hours later.

All of them.
They can beat anybody and lose whenever.
"Oh baby ... what a game!" Brent Musburger, the iconic ESPN play-by-play announcer, yelled in the final minutes of Monday night's back-and-forth affair between Oklahoma and Iowa State.
