Mike Sullivan got some security for Christmas.

The Pittsburgh Penguins have signed their head coach to a three-year contract extension through the 2019-20 season, vice president and general manager Jim Rutherford announced Monday.

Sullivan took over the Penguins job last season with the club outside the playoff picture, and guided Pittsburgh to a 33-16-5 finish, topped with a Stanley Cup victory after a dominant playoff run.

"Mike did the best coaching job in the NHL last season," Rutherford said. "He continues to be a terrific coach and we are happy to give him a well-deserved extension."

Since Sullivan arrived, he's gotten the most out of his best player, Sidney Crosby, who's erased any prior doubts of his production, scoring 104 points in 81 games under Sullivan.

This season, Sullivan's Penguins sit second in the NHL with 49 points, with a 22-8-5 record through 35 games.
