You're both wrong. It was Bigby's game of a lifetime that set the offense up repeatedly in the first half. The final stats were tilted toward the running game because the Packers were up the second half and were able to keep it on the ground, running it down the Seahawks thoats. In the first half they were much more balanced. But not to the extent that you could say they used the pass to set up the run. Bigby was the straw that stirred the drink that evening.
