The Cardinals lost offensive coordinator Todd Haley to the Kansas City Chiefs and chose to part ways with defensive coordinator Clancy Pendergast. Bill Davis was promoted from linebackers coach to replace Pendergast, but the offensive coordinator position will be non-existent.
Offensive line coach Russ Grimm will handle the running game, while receivers coach Mike Miller will be the passing game coordinator.
As a former offensive coordinator with the Pittsburgh Steelers, the play calling role isn't unfamiliar to Whisenhunt. But head coaches have enough on their clipboard in every minute of the game and on both sides of the ball, without thinking big-picture as well.
Graves is the shot-caller in the Cardinals organization. The franchise values his contributions, and he thinks Whisenhunt, Grimm and Miller are up to the challenge, so that's the way the wind blows.
The Cardinals like the way its staff puts together game plans and utilized the personnel.
"That's something we've had great success with and hopefully we'll continue with that," Whisenhunt said. "That was the thinking behind why I did that. We have some good young coaches on our staff that deserved the opportunity to move up, and obviously I didn't want to ignore the fact that Russ has been so critical to our success.
"I thought at this point this was the best way to go with how we're structuring our offensive staff. I don't think there is going to be anything different as far as how they work together or the way our offensive plans are put together. I'm very pleased with where we are right now as a staff."
Whisenhunt's primary concern is maintaining the chemistry of his coaching staff. But from what he's seen and what he's done in evaluating the younger coaches and bringing in new faces, he thinks the coaching staff is going to work well for the Cardinals.
