However, Favre's success must be shared with Ahman Green. The running back put Green Bay up early and took an excited crowd out of the contest.
The teams traded punts to start the game, but on their second drive it took the Packers just two plays to take the lead for good. Green blew past Jerry Azumah in route to a 60-yard touchdown run.
The Bears rush defense came in ranked as the worst in football and they did nothing to disprove that as Green totaled 176 yards on the ground on just 19 carries. The Bears inability to stop the run has become an embarrassment to a team that ranked 2nd in the league against the ground game just two seasons ago.
"I think after we perform like that and after a week off, we had a big game coming up and we didn't perform," said middle linebacker Brian Urlacher. "The first half was just terrible. We didn't make any plays."
The defense was not along in their misery.
After a 10-play Green Bay drive resulted in a Ryan Longwell 34-yard field that gave the visitors a 10-0 lead, it was the special teams that failed the Bears.
A third blocked punt in three games gave Green Bay the ball at the Chicago 20. Two plays later Green scored for the second time in the quarter, this time a 6-yard burst up the gut gave the Packers a commanding 17-0 lead.
Mike Green picked a great time for his first career interception. Needing something to turn the game around, he stepped in front of a Favre pass intended for Javon Walker. The turnover gave the Bears the ball at the Green Bay 34.
Despite starting deep in Green Bay territory, the Bears took ten plays to move 21 yards and eventually settled for a 31-yard field by Paul Edinger cutting the lead to 17-3 early in the second quarter.
It wouldn't' be a Bears Packers game without a touchdown pass from Favre. The quarterback hit an uncovered FB William Henderson over the middle for a 14-yard score late in the half. It's the 17th straight game Favre has thrown at least one touchdown against the Bears and the score gave Green Bay a 24-3 lead.
The one bright spot of the first half was nullified by a penalty. Anthony Thomas appeared to score on a 60-yard run, but a holding penalty on David Terrell brought the play back. The Bears rebounded and put three points on the board on Edinger's second field goal to put a small dent in the deficit heading to the lockerroom trailing 24-6.
Edinger's third field goal of the game brought the Bears within 24-9 by the end of the third quarter.
"Paul was excellent kicking field goals, but field goals aren't going to do it," Jauron said. "We need to get it in the end zone."
That's what Anthony Thomas did on the following possession. After having one long run taken away from him, the "A-Train" showed the caboose could still move. Thomas broke into the open field and outran the Packers defense for a 67-yard touchdown, the longest of his career.
Now within one possession at 24-16, the Bears defense looked to do something they had failed all night, stop Ahman Green.
The momentum seemed to be turning to the Bears, but Green broke a 32-yard run on third and one.
"We got back within eight and gave up another big one on third and short," Jauron said of the Green run. "We knew going in that we had opportunities and we had to make plays, and we didn't."
Then Favre put the game out reach with a 9-yard touchdown pass to Javon Walker. His second TD pass extended the Green Bay lead to 31-16.
Just for good measure, Favre threw a third touchdown pass this time a one-yard lob to TE Bubba Franks.
Trailing 38-16 the Bears made a last pitch effort at a miracle comeback. After a Stewart one-yard touchdown made the score 38-23 the Bears recovered an on-side kick with less than two minutes left, but the drive ended with Na'il Diggs made his second pick of the game.
The Bears have been outscored 111-43 in three games and are the only team in the division without a victory. All three loses have been double-digit defeats. Green Bay improves to 2-2 and is in second place behind the surprising Minnesota Vikings who are 4-0.
Under Jauron the Bears had been 3-1 following a bye week.
"They can't go out there and play for us," Urlacher said. "They get us ready to play; we're always prepared. That's why I don't understand why we can't play better. We have busted assignments; we just keep doing the same mistakes over and over."
This time around Favre and Green had something do with it.
"They made the plays and we didn't, that is what it comes down to," Urlacher said. "The whole season we haven't made plays when we had to."
