GREEN BAY, Wis. — Packers coach Mike McCarthy made it official Thursday, announcing that he is relinquishing his job calling plays for Aaron Rodgers and the rest of the Green Bay offense.

The decision was part of a significant shake-up on that side of the ball, where the Packers led the NFL in scoring in 2014 and Rodgers won his second most valuable player award.

McCarthy is handing off the play-calling duties to Tom Clements, whom he promoted from offensive coordinator to associate head coach. Edgar Bennett was named offensive coordinator, while Bennett’s responsibilities as the wide receivers coach were given to Alex Van Pelt, who’ll now coach both quarterbacks and receivers.

McCarthy had called plays since being hired as the Packers’ coach in January 2006.

“It’s going to make us better. I’m very confident in that. That’s why I did it,” said McCarthy, who is entering his 10th season as head coach. “It’s fun to call plays on Sundays. Don’t get me wrong. It’s probably something I enjoyed it more than anything as far as the game. There’s nothing like Sundays. You can’t get what an NFL player or an NFL coach gets on Sunday in another industry in my opinion.

“To go out there and compete against the coordinator or who’s across the field is something I’ve taken a lot of pride in, had success in, really enjoyed. But this change and the confidence I have in Tom and Aaron, I feel great about it and we’ll be better for it.”

McCarthy also promoted Ron Zook to special teams coordinator to replace Shawn Slocum, who was fired Jan. 30.

The sweeping changes come less than a month after the Packers’ 28-22 overtime loss to the Seattle Seahawks in the NFC Championship came, in which Green Bay blew a 16-0 halftime lead and a 19-7 lead in the final five minutes.
