New defensive coordinator Christian Parker confirmed that the Cowboys will operate as a 3-4 base defense, utilizing a versatile "multiple" approach that includes 4-3 spacing and 4-2-5 nickel fronts.
Parker emphasized building the system around the team's defensive line strength, which features Quinnen Williams, Kenny Clark, and Osa Odighizuwa. By dictating play at the line of scrimmage, the team aims to control the pocket and stop the run effectively.
