Nearly every team gets exposed. In 2015 every last Big12 team was exposed
-OU was exposed by Clemson, and a bad Texas team
-Oklahoma St was exposed 3 weeks in a row by Baylor, OU and Ole Miss,
-Baylor was exposed by a bad Texas team
-TCU was exposed by Oklahoma St
Plus ISU was exposed nearly every week of the year. So if you understood football you would understand that nearly every team, even the top ones get exposed.
