First off, both teams are supremely talented on the defensive end. Not only are they well stocked with great players, they play well as a defensive unit. Both have units that are ranked in the top-10 in all defensive categories. They can rush the passer, they can stop the run, and they make sure no quarterback can throw on them. It is scary watching these teams play football. The Cowboys can’t get to that level all in one off-season, but they can focus on one area that helps any defense get better. They need to build up their defensive line. Owner and General Manager Jerry Jones has ignored this area for many years and it is starting to haunt him. Years of letting older players get contract extensions have now created an aging and often injured line that can’t generate a pass rush. That is no way to build a quality defense. Creating a dangerous defensive line will reenergize this defense and help make the entire defense much better. Just look at the New York Giants in 2007 and 2011.
