The Dallas Cowboys have scored just 41 points over three games, but they aren't planning major changes in personnel or in the playcalling operation with offensive coordinator Scott Linehan.

"I think it would be false for me to say this is about playcalling," Jason Garrett said. "This is about everything we're doing offensively, we have to do better. We have to coach better. We have to play better. We have to run it better. We have to throw it better. We have to protect better. We have to do all the things good offenses do and we have to do all of those things better."

Linehan has been the Cowboys' playcaller since 2014. Dak Prescott has thrown for less than 200 yards in nine of his past 11 games, dating back to last season.

Garrett served as the Cowboys' playcaller from 2007-12 before giving way to Bill Callahan in 2013 and Linehan the following season.

"We're not going to go down that road right now," Garrett said. "I have a lot of confidence in Scott Linehan. He's been an outstanding coordinator in this league for a long time. He's been an outstanding coordinator for us. And he's been an outstanding playcaller for us.

"What we need to do is get better on offense and we have to constantly look at ourselves as coaches first at the positions we're putting our players in with our game plans."
