The Packers have signed C/G Duke Preston.  The 26-year old Preston played in 15 games (11 starts) for the Bills last season.  He has now played in 59 games (20 starts) in his NFL career to date.  The 6’5″, 326 pound Preston should push for the starting job in Training Camp this season for the Packers on the interior of the O-Line.  This was a good signing as Preston is just starting to come into his own.
