Manipulating The Cover Down

Versus Baylor in the Big 12 Championship, Oklahoma’s DC, Alex Grinch, showed the versatility of a modern Nickelback.

Most people are familiar with Lincoln Riley’s offensive genius. Since arriving at Oklahoma Riley’s offenses have been at the top of the charts in college football. He has had three different QBs, all of which either won the Heisman (Mayfield/Murray) or went to the ceremony (Hurts). The one thing that has been the thorn in Riley’s side at OU has been the defense.

After Bob Stoops resigned Riley was given a defensive staff that needed to be dealt with. One major issue was that Stoops’ brother (Mike) was the Defensive Coordinator. After two abysmal years, Riley pulled the trigger and made a change. In steps, Alex Grinch, who was seen as a rising star in the defensive community. Grinch had solid defenses at Washington St., and there is your connection to Riley. Everyone knows Riley is a Leach disciple.

Grinch was able to work alongside a powerful offensive mind (Leach) and still be able to keep the hands on the wheel. Wazzu was consistently in the top half of Defensive Efficiency ranking 13th in Grinch’s final year in Pullman. The job Grinch did in Pullman put him on the map. After his stint at Wazzu Grinch moved to Columbus, OH as the co-DC for Urban Meyer’s Buckeyes. There, Grinch would hold down the secondary while Greg Schiano called the defense. Grinch’s success, pedigree, and connection to Leach made it easy for Riley to pull the trigger. He had all the intangibles: a young intelligent coach who had worked under offensive-minded coaches yet was able to show high-quality results.


It is amazing what a year can do. In 2019, Grinch brought a calmness and discipline to the Sooner defense that had been lacking for a long time. In contrast, 2018 would be a year of opposites as the offense was stellar and the defense was one of the worst in the country. The 2018 defense would finish 114th in total defense. Surrendering 6.13 per play (102nd in the nation) while being on the field for over 1036 total plays (2nd in the nation behind Houston). Finally, Points Per Drive (PPD), which factors in the total amount of series played divided by points, was 112th overall at 2.88. That’s almost a field goal a drive! Needless to say, something had to give. Continue reading “Manipulating The Cover Down”

Sacking the Longhorns – OU vs Texas (2019)

The Sooners had a record 9 sacks against the Longhorns in the Cotton Bowl. MQ details three.

Nine. That is how many sacks the Sooners would end the day with against Texas in the 2019 edition of the Red River Rivalry. This would tie a school record and put Texas QB Sam Ehlinger in the negative for rushing (23 for -9). In college, the sack yards come from the rushing, whereas in the NFL, the sacks come from the QB’s passing stats. Ehlinger’s -9 yards on the ground would be his lowest output since his October 21st outing against Oklahoma St. back in 2017. According to ESPN, Ehlinger would end with a measly 46.4 QBR, which is his lowest output since his freshman year (Baylor would rack up an even lower one at 45.7).

Needless to say, the Sooners executed their gameplan to near perfection when it came to rushing the passer and limiting the Texas passing game. Until the matchup with the Sooners, the Longhorn QB had been averaging 3+ TDs through the air a game. Though Ehlinger didn’t throw an interception or have a terrible game through the air numbers-wise (26/38 210), the sacks did the job of disrupting the Longhorns offense, putting them in long-yardage situations all day.

On paper, the game looked to be a shootout with Texas’ and Oklahoma’s offenses in the top 10 in offensive efficiency and both defenses around the middle of the road (OU would finish 3rd and 70th in O & D Eff. while Texas ended up 17th and 60th). There was no indication that the Sooners would dominate the Texas offensive line the way they did. Though, you could’ve seen cracks in the armor versus LSU (5 sack game). Prior to the matchup in Dallas, the Longhorns had given up nine sacks total in five games. Though some of the sacks were scheme related (we will talk about three), most were due to Ehlinger holding on to the ball too long on perimeter screens (x2) or the Longhorn O-line getting out-manned at the point of attack (below).

The Sooners’ Defensive Coordinator, Alex Grinch, arrived in Norman with much fanfare. Though the results so far are not to the elite standard set by the offense, the defense has risen to “respectability.” In 2018, the Sooners were scraping the bottom of the FBS barrel in defense (#104 in DEff according to BCfToys). In little time at all, Grinch has found a way to at least calm the waters in Norman relatively quickly.

Only once prior to the contest with Texas have the Sooners given up more than 30 points in a game (vs Houston – 31 points). In 2018 the Sooners had similar results, with the defense falling apart towards the end of the season, giving up 40+ points a game in the month of November. Only time will tell if Grinch can get the Sooners back to being elite on defense, but one thing is for sure, nine sacks is a lot and definitely something to build on.
