One of the ways the Dallas Cowboys’ new defensive scheme will be evaluated next season is by how much success DeMarcus Ware has moving from outside linebacker to defensive end. Ware hasn’t consistently lined up with his hand on the ground since college. Ware, 30, finished with 11.5 sacks last year. The seven-time Pro Bowler had 35 the previous two years combined and posted a career-high 20 in 2008. On Thursday, Cowboys defensive line coach Rod Marinelli, who had been defensive coordinator for the Chicago Bears the last three seasons, said he thinks the new 4-3 scheme will give Ware a chance to be even better. “I think it’ll aid him a little bit, because your takeoff is better,” Marinelli said. “Your keys are a little more consistent with what you’re doing. That’s my opinion. I see him, I mean he’s an elite rusher right now. I just think the more opportunity he has, doing the same things every day, every week, the repetition, which allows you to become even faster. The sky is the limit for him, I believe.” The Cowboys struggled mightily to force turnovers last season, finishing with 16. Marinelli’s group in Chicago didn’t have a problem in that department, leading the league with 44. During his Wednesday press conference Cowboys coach Jason Garrett called turnover differential “probably the single most important statistic in football.” Marinelli’s front-four will play a significant role in the number of turnovers the Cowboys force in 2013. “I put a tremendous amount of pressure on myself and the player on one-on-one wins, because the back row, we’re leaving them hung out,” Marinelli said. “They want to break on the ball. And they want to make plays on the ball. But if that guy reloads, reloads, it takes away their aggressiveness. So it’s my job to help those guys trust the rush by, not by talking about it, but by seeing it on tape.”
