combing through the play by play, especially early, once the Packers got close to goal to go situations they got too conservative at times. Specifically that 3rd and 1 followed by the 4th and short "stop" (I think they got jobbed on that spot, but you can't leave room for refs to screw you when you're the underdog) - If the Packers planned on going for it there, 3rd and 1 would've been a perfect time for a play action pass, and instead the playcall was a dive right into the heart of the defense that was selling out on the run.
The very next drive the march down the field and have 1st and goal from the 9, only to run for nothing, then pass to Jones to lose 2 yards, then another underneath incomplete pass to Kraft that had no chance of scoring. Would've rather seen more aggressive playcalling with a pass on 1st down there.
The last 4 Packer possessions went INT (bad short crossing route behind Kraft), 3 and out (bad short throw over the middle to Jones), missed FG (short passes and stuffed run with no chance of moving the chains after Jones' big run), and INT....besides Jones big run, the Packers did nothing offensively to take the game away from the 49ers and it cost them. None of those series included any pass plays beyond a few yards downfield, with the exception of that terrible decision by Love to throw against his body downfield to end the game instead of just throwing it away or running out of bounds for a minimal gain. They got conservative once they went up 7 against a defense that was ratcheting up the pressure and it cost them, because in a way it got Love playing tentative, too.
