Oklahoma’s defense was flat-out awful in 2018, as we know. The Sooners were 114th in total defense (453.8 yards per game), 102nd in yards per play (6.13) and 101st in scoring (33.3 points per game). Their ineptitude indirectly handed Kyler Murray the Heisman Trophy as the Sooners’ signal caller had to pull his rabbit out of a hat on a weekly basis throughout the fall, but without Murray’s exploits Oklahoma might’ve been a 7- or 8-win team in 2018.
Murray is gone, so the defense has to improve or Oklahoma will take a significant fall in 2019.
Lincoln Riley has spent the past three weeks reshaping his defensive staff, and on Sunday he finalized his staff and their assignments.
New hire Alex Grinch will coach safeties while coordinating the defense. He spent 2018 as co-defensive coordinator and safeties coach at Ohio State. (The Buckeyes’ pass efficiency defense slipped from 13th to 42nd in Grinch’s one season on staff, but Riley hired him for his success coordinating Mike Leach‘s defenses at Washington State.)
Assisting Grinch in the secondary will be cornerbacks coach Roy Manning. He spent 2018 as the outside linebackers coach and special teams coordinator at UCLA but worked with Grinch at Wazzu from 2015-17.
Brian Odom was hired away from Missouri to coach the Sooners’ inside linebackers, where he’ll team with new outside linebackers coach Ruffin McNeill. Riley’s mentor, McNeill is one of two holdovers from the 2018 staff. He was hired upon Riley’s promotion to head coach as assistant head coach and defensive tackles coach but took over the entire defense following Mike Stoops‘ midseason firing.
The only Oklahoma defensive coach to coach the same position from 2018 to ’19 will be defensive line coach Calvin Thibodeaux. The OU graduate has been on staff since 2016, when he returned to Norman as defensive ends coach.
