I know some of you are going to take what I am about to say as an excuse for Rodgers poor play, but its more of an explanation and not meant to try and absolve him of playing poorly yesterday and at other points in the season.
If you know much about Rodgers, the guy is about as cerebral as they come. If you haven't listened to Danica's recent podcast interview of him, you should, it explains a lot about the guy and the way that he thinks. Was about the most candid interview I have heard with him and you could tell he was at ease with Danica doing the interview.

Personally, I think he is frustrated with his receiving corp. as well as frustrated at losing some of his play calling abilities. That frustration effects his play more than it would most QB's and definitely more than it should. Again, not making excuses and trying to say that its OK for him to be that way, but it is who he is. He is much like a golfer who can get into a mental slump and until he starts consistently hitting good shots, he can go in and out of that funk. Many times this season we have seen "the old Aaron" when everything is clicking, but when things aren't clicking his game drops off.
That being said, I don't think Aaron changes who Aaron is. He will continue to be hot and cold and probably only as good as his supporting cast. Hopefully this off season Gute can help improve his supporting cast and Rodgers himself can reflect on what he can do to be a better team leader. Until that time, the Packers Superbowl hopes are going to hinge on everyone stepping up their game, including #12.
