Oklahoma's football program has fired Seth Littrell as the Sooners offensive coordinator. Littrell was in his first season as OU's co-offensive coordinator with Joe Jon Finley, and Littrell had been calling the plays. OU and head coach Brent Venables announced the firing officially on Sunday evening. Finley will take over play-calling responsibilities on an interim basis, and offensive analyst Kevin Johns has been elevated to co-offensive coordinator and quarterbacks coach. "Seth is an all-time great Sooner," said Venables. "He has a deep love for this university and football program, and has poured his heart and soul into both. Despite that, our performance as an offense this season has not at all lived up to the OU standard and I felt a change was necessary now. "The leadership role Joe Jon plays on our team is critical. He has the confidence of our locker room and coaching staff, and I'm thankful to him for taking on this expanded role in the middle of the season. Kevin joined our staff last spring as an offensive analyst after serving as an offensive coordinator for over a decade. He has a wealth of experience coordinating offenses and coaching quarterbacks, and I'm looking forward to the fresh approach he'll bring and the bigger role he'll play in offensive game-planning. I'm confident Joe Jon, Kevin and the rest of the offensive staff will work tirelessly to put our players in positions to succeed and make us more effective on that side of the ball." The Oklahoma offense is averaging just 288.1 yards per game, the fewest by a Sooner team since 1966, and OU ranks 128th in the nation in total offense. Littrell played for OU and was on the 2000 national championship team. Littrell was an offensive analyst at OU last season and before that, was the head coach at North Texas for seven seasons.
