Big plays on defense helped Oklahoma ward off a Kolar-esque Cyclone attack and capture a 28-21 win over Iowa State on Saturday.

A hard hit on ISI QB Brody by cornerback Lawrence Key dislodged the ball and allowed Jalen Redmond to scoop and score on a 42-yard fumble recovery to give the Sooners a second quarter lead that the Cyclones were never able to overcome.

But with 2:57 left in the game, Iowa State managed to narrow the gap, scoring on a two-yard Purdy-to-Kolar pass that capped a 75-yard drive made up mostly of passes to the Norman North alum Charlie Kolar.
