The anatomy of an NFL offseason roster is one which changes regularly. The 90-man offseason roster will have several additions and subtractions to it throughout the offseason based on team needs, player availability as well as potential injuries which can occur. Either way, teams around the league who are already offseason mode have begun signing players to their offseason roster.
The Pittsburgh Steelers are no different, and they continue to add depth at positions of need. The linebacker position just got some depth by way of the team signing linebacker John Simon to a Reserve/Future contract.
