It's only special teams that are keeping the 49ers slightly ahead, as two booming punts by Andy Lee (averaging over 62 yards per punt!) helped pin Seattle back. Then after Seattle was forced to punt from deep in their own territory, Ted Ginn Jr. managed a 31 yard punt return to get to the Seahawks 27. This set up a David Akers 27 yard field goal and put San Francisco up 3-0.
After Seattle got the ball back, Jackson was hit from the blind side by Parys Haralson, jostling the ball open, and Will Tukuafu scooped open the fumble. Alex Smith couldn't do much with that red zone opportunity though, and the Niners had to settle for another chippy Niners field goal. It's 6-0 midway through the second quarter.
After the first drive where the Seahawks picked up two first downs, the offense has stagnated. Tarvaris Jackson seems to enjoy hanging onto the ball a little too long. Jim Harbaugh enjoys running the ball a lot--on every third down, regardless of distance, they've rushed the ball.
