Change is not a word associated with the Pittsburgh Steelers, but that is exactly what the defense will face in 2015 as it undergoes its most significant transition in over a decade.
Gone is its architect, Dick LeBeau, as well as defensive icon Troy Polamalu. So is vocal leader Brett Keisel. Keith Butler was promoted to take over as defensive coordinator. The unproven Shamarko Thomas will compete to start at strong safety, while Cameron Heyward figures to become one of the team’s vocal leaders.
These are only a few of the changes that the Steelers will make to their defense.
