One of the more fun things to follow through training camp and the preseason so far for the Dallas Cowboys has been the development of Mike Zimmer’s defense, taking over as coordinator after a three year absence from the NFL entirely. Each practice, scrimmage rep, and preseason snap has helped unravel the mystery of what exactly this defense might look like - but the prevailing trait is that they are going to keep opposing offenses, and those of us covering it, on their toes. Veteran DT Jordan Phillips made his team debut on Saturday against the Raiders, playing ten snaps and making a stop against the run in the first quarter, but the newest member of a defensive line completely rebuilt to play better run defense is not here to just plug holes between the tackles.
