AMES, Iowa (AP) — Four years ago, Iowa State dashed Oklahoma State’s national title hopes on a chilly night in November. An equally poor performance on Saturday in Ames would probably doom the Cowboys again; even with Baylor and Oklahoma still left on their schedule.

No. 5 Oklahoma State (9-0, 6-0 Big 12) could have a clear path to a playoff spot — despite being ranked just eighth by the committee — after trouncing previously-unbeaten TCU 49-29 last week. But with so much competition for the top four slots, the Cowboys can’t afford to look past Iowa State.
