Iowa State at No. 18 Oklahoma (11 a.m. Saturday, Fox Sports 1): Oklahoma is in great need of an offensive spark. The Sooners (7-2, 4-2 Big 12) lack big-play capabilities and were trounced by Baylor 41-12 last week. Things aren’t dire yet, however. Oklahoma should be able to take advantage of Iowa State (1-8, 0-6) at home before the final two weeks at Kansas State and Oklahoma State. With Baylor, Texas and Oklahoma State all playing each other in the final weeks, the Big 12 race is far from decided.West Virginia at Kansas (11 a.m. Saturday, FSSW): With the top Big 12 teams all battling it out in the final weeks of the season, that means the bottom teams are facing off as well. West Virginia (4-6, 2-5) is still fighting to become bowl eligible. With a win against Kansas (2-7, 0-6), which is in the middle of another dismal season, the Mountaineers will be set up to reach a bowl game. West Virginia’s season finale will be a home matchup against Iowa State, which, like Kansas, is winless in conference play.
