The Pittsburgh Steelers parted ways with former long-time defensive coordinator Dick Lebeau at the conclusion of the 2014 season, thus opening the door for linebackers coach Keith Butler to take the reins of a group much in need of improvement. Butler and head coach Mike Tomlin have periodically employed a Cover-2 scheme in training camp and throughout the preseason in an attempt to rectify some of the issues facing a unit that ranked 18th overall in 2014.
Butler and Tomlin have used the team's four preseason games to experiment with the new Cover-2 scheme, and the results haven't been pretty.
