I started digging up some numbers to share on Twitter (follow me @wiltfongjr by the way!) about the improvements made by the 2011 Baltimore Ravens when they hired Chuck Pagano as defensive coordinator. My Twitter thread got so big I figured it best to write it up here at WCG too.
In 2010 the Baltimore Ravens were 12-4 (2nd in the AFC North) and they had a damn good defense that was coordinated by Greg Mattison. In 2011, Mattison left to coordinate the defense of the Michigan Wolverines, so the Ravens named Pagano as their new defensive play caller.
