Josh Jackson scored 18 points and Frank Mason III added 16 to help No. 3 Kansas beat Texas 77-67 on Saturday night to secure its 13th consecutive Big 12 regular season championship outright. Devonte Graham and Dwight Coleby added 12 points apiece for the Jayhawks (26-3, 14-2 Big 12) who have won six straight games. Coach Bill Self said the victory over TCU on Wednesday to earn at least a share of the title was bigger than the win at Texas. Andrew Jones added 18 for the Longhorns, losers of five straight games. Texas did, however finish in a first-place tie with the Jayhawks during two of these 13 straight Kansas Big 12 regular season championships - in 2006 and 2008. The Longhorns are 4-4 in Big 12 home games. Coleby's 12 points matched a career best for the 6-foot-9 junior who transferred to Kansas from Mississippi and sat out last season to regain his eligibility. Coleby missed a season of practice time after tearing the ACL in his left knee in September 2015.
