Oklahoma State gave up over 700 total yards against Oklahoma, but the defense was still able to generate pressure against Kyler Murray and the Sooners. They did so by effectively using man coverage against the offense, which prevented the Sooners from getting any easy yardage.
The Cowboy pass defense played significantly better in the second half (with the help of some Sooner penalties). Their go-to coverages were Cover 1 press man or matchup zone — usually with a five-man pressure — and they used it a number of times to generate pressure on Kyler Murray.
Watch here how OSU plays man across with one high safety and the defense gets a coverage sack.
