David breaks it down over at Niners Nation:
The 49ers had an overall solid first half of play this afternoon. Alex Smith had a fairly solid performance, especially on the first drive of the game. The defense was also quite solid, although there are certainly continued concerns with some of the more mobile quarterbacks in the league. Tavaris Jackson didn’t exactly destroy them, but he had some success. However, aside from one bend-but-don’t-break drive, the 49ers defense looked solid.
