Oklahoma State's defense was the major reason the Cowboys notched an impressive season-opening victory over Georgia.
The Cowboys will be facing another kind of challenge this week against Case Keenum, who passed for 359 yards and four touchdowns in last week's victory over Northwestern State.
Georgia was about as subtle as a punch in the stomach as it attempted to bull through the Cowboys. And after an 80-yard drive to start the game, the Bulldogs produced only 177 yards for the rest of the game.
Oklahoma State's defensive could be influenced the status of their starting safeties. Victor Johnson or Johnny Thomas will start at strong safety for Markelle Martin, who is hobbled with an undisclosed injury. And Oklahoma State free safety Lucien "The Punisher" Antoine told me after last week's game that he was sore, but expects to play today.
I just looked at Antoine going through his warmups with his teammates before the game. He looks ready to play.
One key player that Oklahoma State will have to account for is freshman running back Charles Sims, who had a breakthrough game for the Cougars last week. Sims produced six receptions for 128 yards.
Houston offensive coordinator Dana Holgorsen will likely try to isolate Sims against the slower Oklahoma State linebackers.
