No. 3 Oklahoma entered Big 12 conference play against Kansas State with hopes of reaching the Big 12 Championship Game and College Football Playoff. Those dreams still exist, but now the Big 12's top team doesn't look so invincible following a surprising 38-35 loss to the Wildcats. The upset marks Kansas State's first road win vs. an AP Top 3 team in program history and the second straight win over Oklahoma. Additionally, Chris Klieman became the first coach to beat Oklahoma twice since Lincoln Riley took over as head coach. This was a total implosion by Oklahoma and there's really no other way to look at it. The Sooners had a 21-7 lead at the half and at one point led by 21 points with just a couple of minutes remaining in the third quarter. To lose like this -- again -- to Kansas State is not only a rough look for the Sooners, but for the Big 12's depth as a whole. Keep in mind that K-State was down seven starters due to COVID-19 concerns and contact tracing.
