The Cowboys are switching to a 3-4 base defense for the first time since 2012 under new coordinator Christian Parker. Parker emphasized building a flexible, multiple system around the team's defensive line strength.
Parker, who previously worked with Vic Fangio and Vance Joseph, plans to mix 3-4 fronts with 4-3 spacing and 4-2-5 nickel looks. The defensive line features new acquisitions Quinnen Williams and Kenny Clark alongside Osa Odighizuwa.
