Former Dallas Cowboys quarterback Troy Aikman believes that his former club need more continuity in their coaching staff.

The Cowboys are reportedly poised to announce that Scott Linehan will join the team as the passing-game coordinator and call plays for the offense, making him the third play-caller in as many seasons.

Aikman told the Fort Worth Star-Telegram: "There was the thought that last year with the changes that were made on both sides of the ball that there would be improvement, but really there was regression for both units. Now, more changes again.

"Changes aren't necessarily bad, but I think there's something to be said for continuity. But I've been a part of teams that had change that really benefitted from that. Hopefully the Cowboys will as well."

The Cowboys have failed to reach the playoffs in the past four seasons.
