The Dallas Cowboys have wrapped up offseason workouts and are ready to take their revamped defense to training camp.

The Cowboys are going back to the 4-3 after nearly a decade with three defensive linemen and four linebackers.

The roles are simpler for DeMarcus Ware and Anthony Spencer, a pair of linebackers converting to defensive end: get to the quarterback.

New defensive coordinator Monte Kiffin, the 73-year-old who is replacing the fired Rob Ryan, says the plan is coming along but the Cowboys are "not ready right now."

Dallas wrapped up a three-day minicamp Thursday. The first training camp workout is July 21 in Oxnard, Calif.
