### Oklahoma

In January 2019, Grinch joined Lincoln Riley's staff at Oklahoma as defensive coordinator. He spent three years with the Sooners and was able to help turnaround defense that finished 101st in scoring defense and 130th in passing defense, under former defensive coordinator Mike Stoops, who would be fired after giving up 48 points to rival Texas. In 2019, their defense allowed the fewest yards per game, ranking 20th. Oklahoma won the Big 12 championship and advanced to the College Football Playoff semifinals in the Peach Bowl.

### USC

In November 2021, Grinch followed Riley after he was hired to be the next head coach at USC, serving in the same capacity as before. At USC he inherited a Trojan defensive roster that in 2021 finished as one of the worst units statistically in program history, ranking 103rd in scoring defense and well below average in all other categories. In his first year at USC, in 2022, the Trojans had the nation's best turnover margin. This marked a huge improvement over 2021, when the Trojans were ranked 74th in the country in the same category. The Trojans focused extensively on turnovers, ranking third in the country with interceptions from a dozen different players. Tuli Tuipulotu was named the Pat Tillman Defensive Player of the Year and unanimous All-American in 2022. They finished the season 11–3, losing to Utah in the Pac-12 championship game, eliminating them from national championship playoff consideration. Mekhi Blackmon was named All-America and drafted in the 3rd round of 2023 NFL draft.
After a promising start with USC, the 2023 Trojan defense would later allow 293 points over the next seven game stretch and fell to 7–3. Of these seven games, opponents scored over 41 points five times. On November 5, 2023, Grinch was fired as USC's defensive coordinator.
