ATLANTA -- Completing an unusual swap of offensive coordinators, the Falcons hired Dirk Koetter from Jacksonville to replace Mike Mularkey only four days after the Jaguars introduced Mularkey as their new coach.

The Falcons announced the hire on Sunday.

Mularkey, whose Falcons offense was shut out in a 24-2 playoff loss to the New York Giants last week, was introduced as Jacksonville's coach on Wednesday. He hired former Falcons quarterbacks coach Bob Bratkowski to be his offensive coordinator.

The Falcons hired Koetter despite the Jaguars ranking last in the league in total offense and yards passing in 2011. Koetter's offense ranked 29th with its average of 15.2 points per game.

Koetter was hired as Jacksonville's offensive coordinator in 2007. He worked with Falcons coach Mike Smith for one year. Smith was the Jaguars' defensive coordinator before he became Atlanta's head coach in 2008.

Smith said Koetter will bring "a fresh set of ideas to our offense."

"He is bright, he understands the intricacies of the vertical passing game, but he also wants to be able to run the football which is very important in the NFL," Smith said. "I look forward to working with Dirk and have tremendous confidence that he will be a great addition to our team and our coaching staff."

Smith has emphasized a run-first philosophy with Atlanta.

After the Jaguars fired Jack Del Rio this season, interim coach Mel Tucker assigned Koetter the additional role of quarterbacks coach for the final five games of the season.

Jacksonville rookie quarterback Blaine Gabbert and Luke McCown combined for 12 touchdown passes and 15 interceptions. The Jaguars' strength was their running game. Maurice Jones-Drew led the NFL with 1,606 yards rushing.
