The Packers' past problems with dropped balls by their talented group of wide receivers returned at the worst time imaginable.
And while the Packers' defense has been vulnerable all season, giving up far too many yards and big plays, they've typically made up for it by forcing turnovers.
This time, the Packers were the ones giving the ball away.
Green Bay lost three fumbles, including one on a rare giveaway by Rodgers. The Giants also sacked Rodgers four times.
With the Packers trailing 20-10 at halftime but finally beginning to look like themselves on offense to start the second half, Osi Umenyiora swatted the ball away from Rodgers, and Deon Grant recovered the fumble.
"With a 10-point lead, we're going to get after you," Umenyiora said. "And that's what we did."
But the mistake didn't cost the Packers points, and Green Bay cut the lead to seven points on a 35-yard field goal by Mason Crosby late in the third quarter.
The Packers put together another drive early in the fourth quarter, but Michael Boley and Umenyiora combined to sack Rodgers on fourth-down play in Giants territory.
After carving up the Packers in the first half, the Giants' offense hit a lull in the second half. But they broke out of it to drive for a 35-yard field goal by Lawrence Tynes to take a 23-13 lead with 7:48 left to play.
Packers running back Ryan Grant then fumbled after catching a pass and the Giants recovered, taking the ball back deep into Green Bay territory.
Manning then threw a 4-yard touchdown pass to Mario Manningham and the Giants took a 30-13 lead. Rodgers rallied the Packers for a 16-yard touchdown pass to Donald Driver, cutting the lead to 30-20 with 4:46 left.
The Packers then tried on onside kick, but the Giants' Victor Cruz recovered.
Jacobs scored on a 14-yard run with 2:36 left to put the game away.
It was an emotional day for the Packers, who welcomed offensive coordinator Joe Philbin two days after the funeral service for his 21-year-old son, Michael.
Philbin had been away from the team all week after Michael Philbin's body was recovered from an icy river in Oshkosh, Wis. on Monday. A preliminary autopsy showed that he drowned.
"I think deep down, a lot of us wanted to kind of get this one for him," Rodgers said.
