The Packers go into their game at Chicago Sunday tied with the Dallas Cowboys for the best record in the NFC.  They can secure home-field advantage throughout the playoffs with two more wins, and a Dallas loss.  Coach Mike McCarthy says he’s focused on winning the next game,but keeping his eye on the big target.  Nose tackle Ryan Pickett is recovering from a groin injury suffered in the Packers win at St. Louis.  It’s unclear whether Pickett will be ready to play when the Packers face the Bears at Soldier Field on Sunday.
