4. Ravens fire offensive coordinator Cam Cameron and replace him with Jim Caldwell (Dec.10)

A day after a loss to the Washington Redskins, head coach John Harbaugh shook up his coaching staff and nobody could have imagined the move working out any better. In seven games with Caldwell calling the plays, the Ravens' offense averaged 400.6 yards per game and Flacco had 15 touchdown passes and just one interception.
