One of the biggest X factors for the Pittsburgh Steelers’ postseason run is going to be, plain and simply, Sean Spence, the main man being tasked with replacing Pro Bowler Ryan Shazier in the starting lineup for the defense at mack linebacker.
Spence, originally signed in the offseason by the Colts, spent the past couple of months on the couch before being signed after Shazier’s injury, and it has taken him time to adjust by physically and mentally to the game and to the defense, even if it is [very similar to] the one he ran in his first four seasons.
