COLLEGE STATION, Texas — On the game’s second play, running back DeMarco Murray raced through a gaping hole 70 yards down the sidelines to the Texas A&M 16-yard line. Two rushes later, Oklahoma held a 7-0 lead. The running attack continued to hum Saturday, igniting the sixth-ranked Sooners to a 66-28 victory over Texas A&M before 85,603 at Kyle Field. Murray led the way with seven carries for 123 yards, as OU totaled a season-high on the ground with 328 yards. Chris Brown added 117 rushing yards and three touchdowns on 13 carries, and third-string running back Mossis Madu finished with 65 yards rushing. “I felt good today. I had a little more patience and hit the hole hard,” said Murray, who also had seven catches for 63 yards, tying a career high. “Our offensive line did a great job opening up holes.” Since being held to 48 yards rushing in a loss to Texas, OU has averaged 250 yards per outing on the ground over its last four games. That bodes well for the Sooners heading into a Nov. 22 showdown with Texas Tech. Coming into the weekend, the Red Raiders had the nation’s No. 10 run defense.
