The Ravens have removed the "interim" tag from OC Jim Caldwell's title.
Cam Cameron's mid-season replacement will officially be back for 2013. The Ravens have also hired former Eagles DC/OL coach Juan Castillo as their run-game coordinator. Caldwell's return became a formality after the Ravens offense morphed from plodding and predictable to aggressive and consistently productive under his watch. Caldwell has adopted an attacking approach with big-armed QB Joe Flacco, and has taken to spelling Ray Rice often with electric rookie Bernard Pierce.
