GREEN BAY, Wis. (AP) – Stringing wins together was something the Green Bay Packers did with ease last season.  This year, not so much.  Fresh off their rout of the previously unbeaten Texans, the Packers (3-3) head to St. Louis looking to win consecutive game for the first time this season. Coach Mike McCarthy says “back-to-back” is the team’s theme this week.  As impressive as Sunday’s victory was, offensive tackle Bryan Bulaga says the team can’t dwell on that.  ”That game’s over,” he said Wednesday. “Now it’s time to go out this Sunday and do it again. It’s going to be important to do that, and it’s going to be a challenge.”
