IRVING, Texas -- Now that the Dallas Cowboys have developed one of the NFL's best offensive lines, coach Jason Garrett and the front office have started the same process with the defensive line.
In many ways, they are using the same approach they did to re-shape their offensive line.
Since the start of the 2013 season, the Cowboys have released Jay Ratliff and DeMarcus Ware, and let Jason Hatcher leave via free agency. Of the 11 defensive linemen on the roster, eight joined the Cowboys this season.
Defensive end DeMarcus Lawrence (second round), who broke his leg in training camp and should return this month, and Ken Bishop (seventh round) were draft picks. Henry Melton, who missed the last 13 games last season with a torn ACL, signed a one-year deal with a club option for three years and was the only big-dollar defensive player they acquired.
They also signed free agents Jeremy Mincey (30), Terrell McClain (26) and Amobi Okoye (27), who is eligible to come off the non-football illness list for Week 7 before training camp. Mincey signed a two-year deal for $3 million, McClain signed a three-year deal for $3.05 million, and Okoye received a two-year deal worth $1.6 million.
"You’re always trying to bring good players in," Garrett said. "We had some big decisions to make last year from an organizational and salary-cap structure. Those are hard decisions when guys have been good players and you have to move on from them.
"I think we’ve done a good job, both in the draft with young players, but also with some veteran players and the guys already on the team to create that competition and challenge those guys."
The Cowboys have used an eight-man defensive line rotation during their first four games, which means three players sit each week. It wasn’t that tough the first couple of weeks, because the Cowboys had one or two defensive linemen who couldn’t play because of injury.
That is not the case this week, when just about everyone is healthy enough to play.
"We have an eight-man rotation. Who are going to be the eight? It’s up for debate every week," Garrett said. "You want guys to have to earn those spots. You have to earn it on Sunday, and you have to earn the right to dress on Sunday."
