Of the nine coaching staff members (not counting Riley) present at the time Stoops stepped down Oklahoma is down to just four holdovers and only one (Calvin Thibodeaux) from the defensive side of the ball.
It started when longtime strength and conditioning coach Jerry Schmidt left for Texas A&M before the 2018 season. That was followed by defensive coordinator Mike Stoops’ dismissal middle of last year. In recent weeks linebackers coach Tim Kish retired in the offseason and Kerry Cooks moved on to coach at Texas Tech.
What’s interesting to note is each of these coaches were replaced by a younger man.
