During the 2012 offseason, the Steelers began somewhat of a youth movement on the defensive side of the ball. That movement included the axing of longtime stalwarts Aaron Smith and James Farrior.
That trend has continued for Pittsburgh in 2013.
So far this offseason, the Steelers have parted ways with Casey Hampton and Keenan Lewis, not to mention two veteran backups in Will Allen and Ryan Mundy. For a defense that's continually ranked amongst the league's best, overcoming the loss of five starters in two seasons may be a tall task to overcome.
Free agency hasn't accumulated much for the team with the exception of the return of cornerback William Gay. There's still plenty of work to do and Pittsburgh should be very active on defense in the draft.
Even so, we can still get some sort of vague picture of how the Steelers defense may look in 2013.
