When the Cowboys hired Dan Quinn to be their new defensive coordinator, it was essentially a return to the defensive philosophy the team had run in the final two years under the old coaching staff. That’s because Quinn is a branch off of the Seahawks Legion of Boom tree, as was the Cowboys’ defensive play-caller from 2018 to 2019, Kris Richard.
While an in-depth look at the scheme that Quinn runs reveals several nuances, the meat and potatoes of it is very straightforward. It’s a four down-linemen front with little blitzing and a lot of press coverage out of both Cover 1 and Cover 3 shells.
