See Peyton Manning last year.
Seattle's game on the backend thrives not on interceptions but on immediately harassing the receivers. If the QB's accuracy is off even a bit and is not leading his receivers away from coverage and making tight throws, they're immediately pasting the receiver. If the QB floats his throws even a little, the balls are contested and often batted away. Rodgers, while still very good at finding open receivers, did not have his usual drive on the ball. The team was the reason the Packers almost won this game... particularly the OL and the defense... but if Rodgers is healthy the Packers probably score 35 points.
I was disappointed that Lacy was not more successful in the passing game... on the failed screen and the miscommunication, he had a lot of grass in front of him. I thought Jordy had a poor game for him also. He had the ball in the endzone that Rodgers deserves some blame for but that he usually goes after and he had another drop on a first down play that hurt.
