If the Cowboys want to fix their defensive line quickly, looking at the 2005 offseason may provide a workable blueprint for 2016.
In 2005 the Dallas Cowboys drafted four defensive linemen as they switched to a 3-4 defense under Bill Parcells. Bill Parcells had been hired as head coach in 2003, but he didn’t change the defensive scheme until the Cowboys finished the 2004 season ranked 27th in points allowed.
In 2005, the Cowboys had two first-round picks (thanks to a trade with the Bills the previous year), and with their first two picks, the Cowboys selected OLB DeMarcus Ware and DE Marcus Spears.
