Wow, I must admit I thought of many reasons one could argue about why Green Bay lost the game - but an NFL conspiracy against them....
First off, for those Packer fans who are bemoaning the conservative game plan of the Pack in the second half, I give you their opening drive of the game:
Green Bay Packers at 14:55
1-10-GB17 (14:55) D.Wynn left guard to GB 29 for 12 yards (H.Hillenmeyer, A.Archuleta).
1-10-GB29 (14:17) B.Favre pass short right to D.Driver to GB 36 for 7 yards (C.Tillman).
2-3-GB36 (13:35) B.Favre pass short right to G.Jennings to GB 48 for 12 yards (C.Tillman).
1-10-GB48 (12:58) D.Wynn right guard to CHI 8 for 44 yards (D.Manning).
1-8-CHI8 (12:24) D.Wynn up the middle to CHI 7 for 1 yard (T.Harris).
2-7-CHI7 (11:42) (Shotgun) V.Morency right guard to CHI 2 for 5 yards (L.Briggs).
3-2-CHI2 (11:05) D.Wynn up the middle for 2 yards, TOUCHDOWN.
5 of 7 plays were runs. Three of those five runs were for 5 yards or more (the 4th ended because he was in the endzone).And here are
second three drives in the second half (with the score tied 20-20):

There were, in those 3 series, 8 passing attempts in 9 plays (9 out of 11 if you count the two plays in which penalties were charged). This was, of course prior to the final drive of the game which consisted of 8 straight passes by Favre - which would have brought the total to 16 of 17 passing plays for GB in the entire 4th quarter.To be fair, the Packers had ripped the Bears in the first half to the tune of 102 rushing yards. To say "Why did Green Bay come out and run the ball with a 17-7 lead??" is just silly. They ran the ball because they had been averaging 7.9 yards per rush in the first half! (That and Jones can't have the ball stripped if they're handing to Wynn and Morency) - and the clock keeps running. Given Favre's familiarity with picks and the early success of the Packer running game, I would think it would be obvious why they would try to come out in the second half and run the ball. Incidnetally, the first drive of the 3rd quarter for the Packers started on the BEARS 33 - already field goal range.
Unless my math is horrible, the Packers ran 9 times and passed 18 times in the second half - in which they were either leading or tied until 2:05 left in the game. Hardly what I would consider an "NFL Issued Ultra-Conservative Conspiracy Game Plan to Lose To The Bigger Market Chicago Bears".
The Packers lost because they turned the ball over 5 times - 4 on offense and 1 on special teams. It's that simple. The refs, nor the NFL forced J. Jones to fumble twice, nor did they brainwash Favre into throwing an ill-advised pass right to Urlacher deep in his own territory, nor was the ball manipulated into Brad Maynard's hands on the punt return fumble.
