Felt to me like the Niners should have won this game by more than one score -- they out-gained Green Bay 494-385 and had a +2 turnover differential. 11 penalties was a big part of that, as were a missed field goal and two long drives that ended in field goals.
Seemed to me like Green Bay was terrified of Kaepernick scrambling, so they played a lot of zone coverage to limit his running lanes. The result was a) limited pass rush, and b) holes in the zone for Boldin to slip into. The O-line did a very poor job run-blocking (the GB defensive tackles had a strong game) but pass protection was good. Seattle will play a lot more man coverage next week and SF will have to run the ball much better. But wow, Kaepernick is a talent. His accuracy was really impressive.
On the other side, they let Rodgers get his yards, but they mostly limited big plays and GB couldn't run the ball at all. Tackling was surprisingly poor at times. The pass rush was inconsistent, Aldon Smith had two sacks but didn't do a whole lot else. Ahmad Brooks was invisible. Part of that was the 49ers rarely blitzed. Eric Reid had a good game, Asomugha not quite as much. But you're never going to shut down Rodgers.
Before the season I thought splitting the first two games was a reasonable expectation. They've already got the first one in the bag. A win next week would put them in pole position for the #1 seed.
