Welcome back to our weekly illustrated guide during the college football season to four games that had an impact on the playoff race.
Big Game Bob reappeared in Waco, Texas, as Bob Stoops and the Sooners muzzled the previously undefeated Bears to end Baylor's 20-game home win streak and, likely, playoff hopes.
The Ducks took down the Cardinal and likely crushed Pac-12 playoff hopes in the process. Oregon's offense rebounded to form, with 436 yards on 48 plays, for an average of 9.1 yards per play and the most allowed by Stanford this century.
Can you hear the Hawkeyes now? Iowa stayed alive in the playoff race by holding off the Gophers to become 10-0 for the first time in school history. The Hawkeyes can clinch the Big Ten West and a spot in the league title game with a win over Purdue next week.
The Cowboys escaped the curse of Ames, Iowa, which felled Oklahoma State in 2011. Then, the 10-0 Cowboys were No. 2 in the country and lost to Iowa State on the road. On Saturday, the 9-0 Cowboys trailed the Cyclones by 10 points in the fourth quarter but remained one of five undefeated teams in the country (along with Clemson, Ohio State, Houston and Iowa).
