Kansas’s Division I-record 14-year streak atop the Big 12 ended on Tuesday night when the Jayhawks fell to Oklahoma 81-68 at the Lloyd Noble Center in Norman. The defeat left Kansas State and Texas Tech as the two Big 12 teams left vying for the regular-season championship, denying the Jayhawks at least a share of the conference title for the first time since March 2004. Fans in Stillwater, Austin and Waco likely spent much of their night dancing on the Jayhawks’ grave.
