Houston (CBS Houston) – The forecast for Sunday’s game is calling for snow and near freezing conditions at Lambeau Field. The Texans will get a true test of the frozen tundra, but it’s the weapons that the packers have offensively that provide their biggest concern.

As with most offenses, it always starts at quarterback, and despite some struggles this season, Rodgers is still one of the best. Rodgers, along with his arm, also possesses a scrambling ability that allows him to improvise and create plays that are initially well defended.

“He’s been doing it a while and has tremendous ability. As well as being able to throw the ball, and make the throws and throw accurately, he has good run ability,” Texans defensive coordinator Romeo Crennel said.

Rodgers has been heating up as well as he’s thrown for over 300 yards in three straight games, and has five touchdowns and no interceptions in the last two.

Green Bay head coach Mike McCarthy uses a lot of different formations and players in non-traditional positions that make it difficult for defenses.

“It’s hard to decipher which direction they’re going. How to call the strength of your (defense) relative to their offense. We’ve practiced hard yesterday and today. We know it’s going to be a challenge,” said Texans head coach Bill O’Brien.

The Packers offense also provides their quarterback with a lot of tools at his disposal.  From Jordy Nelson, to Randall Cobb to Davante Adams and Ty Montgomery.

“He’s got a handful of weapon, he’s got some tight ends that can catch and run after the catch. He’s got several receivers, and they use them all. They’ve got a five wide receiver package that they can put in there and then one of the wide receivers is also a running back,” Crennel said.

Despite a slow start, Green Bay’s offense is 11th in the league in scoring and trending up. The Texans coaching staff is aware of all the things that makes the Packers click on offense.

“Great players at a lot of different spots, especially at the receiver position. Very athletics tight ends, and obviously a great quarterback, different personnel on every play, formations, motions, all the adjustments that go with it,” O’Brien said. “You have to deal with all the different cadences Aaron has. There’s just a lot.”
