'The Ravens did add one piece, Harbaugh announced. They have brought on former Philadelphia Eagles defensive coordinator Juan Castillo as a consultant.
Castillo became the Eagles defensive play caller after 13 seasons as an offensive line coach, a rare move. But the change did not work out as well as Head Coach Andy Reid wanted, leading to Castillo's dismissal on Oct. 16, in his second year on the job. Castillo's talent-rich defense was ranked 13th in points allowed per game in the NFL when he was fired.
Castillo will serve as a consultant for the remainder of this season and as the Ravens' run-game coordinator next year.'
