Jon Machota of the Dallas Morning News reports that new defensive coordinator Monte Kiffin told both Jason Hatcher and Brandon Carr to study the Seattle Seahawks defense in anticipation of what the Cowboys defense could look like in 2013. The article quotes Brandon Carr: "I kind of asked him what our philosophy and what the look of our defense was going to be, and as a prime example he said, ‘Go see Seattle film and you’ll probably learn a lot from those guys and just watch how they move on the field.’ That’s some homework for me to do for the next couple of weeks." The Seahawks are one of the hot teams right now that everybody is looking at after their defense led the league in points allowed with 245. That's 155 points less than the 24th-ranked Cowboys. But Kiffin's advice to his new players isn't simply based on emulating the top defense in the league. Rather, it's based on the fact that the Seahawks are playing an updated version of Kiffin's Tampa-2 / 4-3 Under defense.
