The Packers had trouble getting their vaunted offense going for the majority of their opener, and their defense wasn't much better from a unit that was historically bad the year before.
The first half was mostly a defensive struggle, with 49ers kicker David Akers hitting three field goals to stake San Francisco to a 16-7 lead. Akers hit a field goal as the half expired from 63 yards out, a new career high. The ball bounced off the cross bar but advanced past the bar on the bounce, giving the Niners a nine-point lead.
The Packers got a late touchdown to James Jones in the 4th quarter but couldn't score on their last drive of the game, turning the ball over on downs in the final minute. Aaron Rodgers was 30/44 for 303 yards and two touchdowns. Green Bay averaged only 3.2 yards per carry, and their running backs only attempted nine carries (all by Cedric Benson).
