The defense disappointed, as it seemed to lack any coherent plan on how to stop Frank Gore when he got to the outside and allowed the 49ers to run away far too early in the game. There was some poor tackling and a few questionable angles by the secondary, but really, that wasn't as big a concern as the real problem.
Where was the offense?
Aaron Rogers' 303 yards and two touchdowns are deceptive, as he was unable to attack the Niners with his biggest weapons: Greg Jennings and Jordy Nelson.
He was able to make good use of James Jones and Randall Cobb, but Jermichael Finley dropped several passes which could have been critical to getting the offense moving earlier.
The other disappointing aspect of the offense was the lack of run game. Whether it was Cedric Benson's two yards per carry or his meager nine attempts, the Packers could never get the run game going, and when they fell behind, they jettisoned it altogether.
Against the Bears, the Packers will need to amp up their offense earlier and find ways to get into the end zone, not just the red zone. Something they failed to do at all on Sunday.
There were some positives offensively. Randall Cobb had a big day and looks to have fully stepped into Donald Driver's shoes. James Jones showed some of that impressive talent with his four catches for 81 yards, but had numerous drops that were all too familiar.
Still he showed why they keep him around. When Greg Jennings and Jordy Nelson are struggling, it's good to know there are players to fill in.
Defensively, it was a mixed bag. On the one hand, they definitely pressured the quarterback with Charles Woodson and Clay Matthews combining for four sacks.
On the other hand, the secondary looked like a big, jumbled mess. I was watching this with The Go Routes's Aaron Nagler, who, as you might know, has a bit of a thing for the Packers.
At one point he turned to me, and in so many words said that the secondary still didn't know what it was.
After this loss are you:
He's right. You look at the secondary and there seems to be little cohesiveness right now. There's talent there, yes. However, are they in the right positions to make plays?
They will have to get it together against a Bears team which will smell blood in the water and want to wash the taste of a win against the Colts that was harder at some points than it should have been.
As for Sunday, the Packers left Lambeau Field knowing there was still plenty of work to do.
