The Pittsburgh Steelers have signed 36-year old punter Mitch Berger to compete with Paul Ernster for the starting punter job.  Berger played in 5 games for the Cardinals last season and he averaged 40.7 yards per punt with a net of 33.1 yards.  He placed 6 punts inside the opposing 20-yard line (30%) and he only had two touchbacks (10%).  This will be an interesting battle for the starting punting gig between Berger and Ernster with Berger probably holding a small edge due to experience.  Berger has now played in 164 games in his NFL career and he has averaged 43.1 yards per punt with a net of 37.7 yards.  He has placed 233 punts (31.9%) inside the opposing 20-yard line in his career and he has had 72 touchbacks (9.9%).  This was a solid signing for the Steelers as Berger could win the job outright.
