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.

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”
