According to Adam Rittenberg, Jim Knowles will join Ryan Day's staff at Ohio State.
Day will have a third defensive coach in three seasons.
The most important thing at the moment is that our players are in the best position to win the Rose Bowl. The current staff of 10 assistant coaches will continue to plan and prepare for the game.
Oklahoma State's defensive coordinator for the past four seasons, Knowles was a finalist for the Broyles Award in 2021, which is given to college football's top assistant coach.
Oklahoma State's defense is third in the nation in yards per game. It ranks seventh in scoring and fourth in yards per play. Oklahoma State leads the way in third-down defense, a category in which it led in 2020.
The Cowboys allowed 273.6 yards per game in 2021, with 89.2 yards on the ground and 184.4 in the air.
The Ohio State team allowed 366.6 yards per game in the 2021 season, which ranked 52nd in the country. In addition to the passing yards per game, the Buckeyes defense allowed 119.7 rush yards per game. The team's defense gave up 401.9 yards per game in 2020, the second-highest mark in the school's history.
In 1988 he began his coaching career at Cornell and later served in various roles until he was hired as the defensive line coach at Western Michigan in 1997. He was promoted to defensive couthing in 2001 and remained there until 2002.
After working for Ole Miss as a recruiting and linebackers coach, he joined Duke as a defensive coach.
One member of the Ohio State coaching staff will need to leave the program so the school can remain under the allowed limit for assistant coaches.
