The Pittsburgh Steelers have signed center Justin Hartwig to a 2-year, $3,725 million dollar contract.  Hartwig will likely be the starter at center from day #1 this season and he is a big guy at 6′4″, 312 pounds which is the kind of size the Steelers’ like on the O-Line.  Hartwig started 15 games for the Panthers last season.  Hartwig has now played in 67 games (63 starts) over his six year NFL career.  This was a good move for the Steelers.
