Big 12 Conference play has arrived.
Six of the league's 10 teams are still undefeated, though that number will quickly be trimmed by at least two.
On the first Saturday with a full slate of five conference games, there are two matchups of undefeated teams. No. 23 West Virginia plays at No. 15 Oklahoma this weekend, while Kansas State goes to No. 20 Oklahoma State, which opened conference play with a win at Texas on Saturday.
Oklahoma coach Bob Stoops said Monday that things have worked out so far for the Sooners, including a win at Tennessee.
The other undefeated teams are defending co-champions TCU and Baylor.
