Three weeks of practice down, three weeks to go before things get serious around here. The Packers are still working shorthanded but Mike McCarthy got in a solid two hour plus practice in pads today for the first time in nearly a week.   The defense came up with most of the big plays, in one team period, Brad Jones and D.J. Smith came up with back to back interceptions, but in a no huddle period, Aaron Rodgers directed another touchdown drive, an excellent bootleg around right end capped it off to the delight of the Ray Nitschke Field fans.  In the final period, a two minute drill operated by Graham Harrell, the offense went nowhere, an incompletion, a five yard sack, a throw away and a Dion Turner interception that he tipped to himself to finish the practice off.  Cedric Benson worked for the last time in shorts and a helmet, he'll go full pads when the team returns to practice after the Browns game on Sunday.  It was a big day for T.J. Lang.  The Packers announced he had signed a contract extension and while the financial details weren't disclosed, there's talk it's a deal with a five million dollar signing bonus and base salaries in that ball park for the next four years.  Lang was all smiles walking from the practice field to the stadium with his girlfriend alongside and his one year old son John resting on his shoulder, taking in a nap. The 4th round pick from Eastern Michigan in 2009 got off to a rocky start, a jack of all trades but master of none, starting games at tackle and guard in emergencies.  Last year he grabbed the starting left guard spot and with Josh Sitton re-upped a year ago, the Packers have locked in their two inside offensive linemen through the peak of Aaron Rodgers' career.   After dealing with the death of his father last year,  Lang says he's planning on buying a new house for his mom and little brothers.  On the link below, comments from Ted Thompson, McCarthy and Lang on his new deal.
