OWINGS MILLS, Md. — Gary Kubiak was bored and in need of a job, if for no other reason to give his wife some breathing room at home.

At the same time, the Baltimore Ravens were in the market for someone who could add some spice and efficiency to the NFL’s 29th-ranked offense.

Both sides got what they wanted Monday when Kubiak was hired to be the Ravens’ offensive coordinator. Kubiak replaces Jim Caldwell, who was hired on Jan. 14 to coach the Detroit Lions.

The 52-year-old Kubiak was Houston’s coach from 2006 through last month, when he was fired.
