Oklahoma is in good shape at the interior positions; Seniors Adam Shead and Bronson Irwin each played well despite some nagging injuries last season, and Tyler Evans and Nila Kasitati will both be back from ACL tears. If needed, Ty Darlington could easily take over the center position, allowing Gabe Ikard to play guard. Junior-college transfer Dionte Savage could also contribute.
3. New faces on the coaching staff
Bob Stoops' coaching staff is filled with the hiring of former Auburn assistant Jay Boulware, who will coach tight ends and special teams. Stoops also added offensive line coach Bill Bedenbaugh and defensive line coach Jerry Montgomery, who came from West Virginia and Michigan, respectively.
All of the new coaches inherit position groups in need of improvement. In Oklahoma's three 2012 losses, it was beaten in the trenches on both sides of the ball. The tight end position became largely irrelevant last season — in part due to Oklahoma's abundance of wide receivers — but also because the tight ends on campus failed to produce and/or stay healthy.
