Oklahoma State defensive coordinator Jim Knowles has led the Cowboy defense to improve consistently over the past four years and the unit has now become one of the most dominant in the nation and in the history of the school. His performance on the field speaks for itself as the Cowboys rank among the national leaders in 3rd Down Conversion Defense (No. 2), Total Defense (No. 3), 10-plus Yard Plays Allowed (No. 3), Rushing Defense (No. 4), Team Tackles for Loss (No. 5), First Downs Defense (No. 5), Yards Per Play Allowed (No.6) Scoring Defense (No. 9),Team Sacks (No. 11), Team Passing Efficiency Defense (No. 14) and Defensive TDs (No. 15). The Cowboy defense is also No. 1 in the conference in every one of those categories and more. (Rankings as of November 10) Knowles’ performance off the field is just as deserving, as he is universally loved by the players he coaches for his knowledge of the game, his skill as a play-caller, his coaching style and several aspects of his quirky personality. While Oklahoma State was known for its offense for decades before Jim Knowles arrived, he came to Stillwater with a goal for the Cowboy defenders to make the program known for its defense, and he has succeeded in that goal far beyond what most thought was possible.
In 2020, OSU led the nation and third down defense and they have taken that momentum into every area in 2021. Here’s how the Cowboys have improved each season under Jim Knowles and how the 2021 numbers compare in school history at the bottom:
