Five storylines to watch in Week 12 in the Big 12:
Can Gibson's defense slow Oklahoma's triplets?
West Virginia's defense has been one of the surprise units in the Big 12, which has helped propel the Mountaineers into conference title contention. This, however, will be the toughest test of the year for defensive coordinator Tony Gibson's bunch. Because of their balance, featuring Joe Mixon and Samaje Perine in the backfield and Baker Mayfield and Dede Westbrook through the air, the Sooners are a load to defend. And unlike in recent seasons, this Mountaineer squad is not necessarily built to win shootouts.
