With 4:09 remaining in the fourth quarter, the No. 6 Oklahoma Sooners' defense took the field with only one mindset: force a three-and-out and give Landry Jones and the offense one last shot to win the game.
Following a 10-yard touchdown grab by Sterling Shepard, the Sooners only trailed the No. 15 Kansas State Wildcats 24-19.
However, in what was a trend all game long, the Wildcats converted on third down. Twice.
With that, the Sooners' early season mistakes finally caught up with them as they fell 24-19.
Gone was the chance of a perfect season.
Gone was the 14-0 home record against ranked opponents under Bob Stoops.
But most importantly, gone was the chance for the Sooners to control their own destiny.
Earlier this week I listed seven keys that the Sooners had to accomplish in order to win.
Here's how they fared.
