It didn't take long for Mike Mularkey to find a new job, just like it didn't take long for the Miami Dolphins to replace Scott Linehan as their offensive coordinator. Days after Mularkey resigned from the Bills, he agreed to become the Dolphins new coordinator.

Linehan, who was the Dolphins' coordinator for just one season, left to become the head coach of the St. Louis Rams. Mularkey becomes the team's fourth offensive coordinator since May of 2004. He'll take over an offense that really improved over a span of one year. In 2004, the Dolphins had the 29th ranked offense in the league. Last year, they were ranked 14th. Their offensive spark helped them finish with a 9-7 record, giving them four more wins than the year before.

Mularkey's resignation from the Bills was unexpected. In two seasons as the Bills' head coach, he was 14-18. Buffalo's offense struggled this year under QB J.P. Losman, and the running game never really got things going.

"It was clear that his teams always played hard and were well-coached in all aspects of the game," said Dolphins' head coach Nick Saban. "He instilled in his players a sense of belief in his system, and those leadership skills will serve him well in his new role."

Mularkey was the Pittsburgh Steelers' offensive coordinator before coming to Buffalo. At Pittsburgh, he was able to guide Kordell Stewart and Tommy Maddox into becoming good quarterbacks during those years.

"His expertise produced an explosive and physical style of play, and he raised the production level of his quarterbacks," Saban said.
