NORMAN, Okla. — Mike Stoops is out as OU’s defensive coordinator, OUInsider.com has been able to confirm. His replacement isn’t yet official, as a source said “Riley will make that known soon.”

Following the latest poor defensive performance, the much-maligned coordinator met with head coach Lincoln Riley and OU President James Gallogly to have a serious discussion. It turns out that serious discussion ended up being the decision that Stoops is out.

Stoops’ Sooner defense gave up the most ever points scored by Texas in the Red River Showdown, as the Longhorns put up 48 points. That included 24 in both halves and more than 500 yards of total offense.

Quarterback Sam Ehlinger abused the Sooners for nearly 400 yards alone and five scores. He threw for 314 yards and two touchdowns on 24-of-35 passing, also rushing for 72 yards and three scores on 19 carries.

The Longhorns went a bit conservative with a 21-point fourth quarter lead, and Stoops’ Sooners came up with three stops, while OU’s offense posted three straight scoring drives in 5:50. That drew them even inside the final three minutes of play.

But the defense would get back to its old ways, permitting a game-winning drive by Ehlinger and co. With a negative play to start the drive, cornerback Tre Norwood was hit with a pass interference penalty. Ehlinger then completed to Devin Duvernay, moving it into OU territory, and he rushed for a first on third-and-3 at the OU 36 when the Sooners badly needed a stop with only one timeout remaining. Cameron Dicker eventually booted through the game-winning 40-yard field goal with only nine seconds remaining.

The embarrassing defensive performance included a pair of conversions when the Longhorns were backed up in third-and-20-plus yard situations. First, Ehlinger threw an 18-yard pass to tight end Andrew Beck, setting up a fourth down conversion, and on another occasion he found wide receiver Lil’Jordan Humphrey for 19 yards, setting up an equal fourth down conversion.

“We didn’t tackle well,” Riley said. “We missed too many big tackles in the open field. I didn’t think we covered great. We had a few too many guys just getting beat to the ball in a couple situations and the glaring thing was the third and longs that we gave up. We gave up a third and 19 and we gave up another third and extremely long and

they carried the ball another 10 yards.

“We’ve got to be better on third downs. We kind of surged there at the end and played extremely well—more competitive and more like we expect to play there at the end, but we gave them too many and that’s something we’ve all got to do a better job with.”

Now the question is where things go from here. Who will take over the reins?
