IRVING, Texas -- Much of the focus of the Dallas Cowboys' offseason has been about how to improve a defense that finished 32nd in the NFL last season.
The Cowboys swapped out defensive coordinators, bringing in Rod Marinelli for Monte Kiffin. They have swapped out players, cutting DeMarcus Ware and losing Jason Hatcher. They lost their best defender, Sean Lee, to a knee injury in May. Their highest-profile free-agent signing, Henry Melton, has not taken a team snap as he recovers from a torn anterior cruciate ligament. The biggest re-signing, Anthony Spencer, might not be able to take a snap in training camp as he recovers from microfracture knee surgery.
Despite the historic defensive deficiencies in 2013, the Cowboys were a Week 17 win away from making the playoffs.
With just a slight improvement on defense, the Cowboys believe they can contend for the postseason.
"I agree," executive vice president Stephen Jones said, "and I think we're better on offense than we were last year."
The Cowboys averaged 27.4 points per game last year, which was fifth-most in the league, but they averaged only 341.1 yards per game, which was 16th. They struggled on third down, converting just 35 percent, and they could not finish games by running the ball or chose not to attempt to run the ball.
Jones believes the offense has a chance to be great in 2014.
"Obviously we believe Tony Romo is an elite quarterback and you put the supporting cast with him, that's why picked Zack Martin," Jones said. "I think we're better in the offensive line and you'd hope so if you spent the 16th pick in the draft on one of the better offensive lineman in the draft. You'd like to hope you're better. And we were pretty good last year and I think we'll move that up to where you say, ‘Hey, we've got a chance to have an elite offense.'"
The pieces are there. Romo threw 31 touchdown passes and was intercepted just 10 times in 15 games. Dez Bryant, Jason Witten, DeMarco Murray and Tyron Smith went to the Pro Bowl. With Martin, the Cowboys have three first-round picks on the line with Smith and Travis Frederick. Wide receiver Terrance Williams proved he could be a playmaker last year and will take over for Miles Austin.
The Cowboys will break in their third playcaller in as many years in Scott Linehan after Jason Garrett and Bill Callahan, but Jones likes the freshness Linehan will bring to the offense. The Cowboys are not overhauling the system, but adding Linehan's wrinkles.
"I think he brings a different look," Jones said. "After a while when it's been Jason's offense and Bill ran Jason's offense and called the plays in Jason's offense but at the end of the day we'd been doing that for a while. I think now to add wrinkles and add things to it, I don't think it's going to be, when people get ready to play us, that they know exactly what to expect now."
