Some things to watch in the Big 12 Conference, which is down to four games this weekend after No. 14 Oklahoma's game at West Virginia was postponed because of positive COVID tests and contact tracing for the Sooners:
Defenses are helping carve a path toward the Big 12 championship game. The two current frontrunners, No. 15 Iowa State and No. 14 Oklahoma, have stood out recently by what they've done to limit opposing offenses. The first-place Cyclones held Kansas State to nine pass completions and 149 total yards in a 45-0 victory over the Wildcats last week.
West Virginia's home matchup with Oklahoma on Saturday has been rescheduled for a later date.
