The first string defense needed a series to adjust to the Chiefs game plan. The 49ers were blanketing the Chief receivers, but was being beaten by mismatched coverages on tight ends and running backs in the middle of the field. After giving up a touchdown on the first drive, the defense held still until late in the third quarter. By that time, the starters were well off the field.

The defensive line was able to exert better pressure this week on the quarterback. Bryant Young, Reggie McGrew, Chike Okeafor and Sean Moran were among the notables. Moran in particular was making some nice plays, but many of his snaps came after the Chiefs first string offensive line had been pulled. Moran even forced a fumble, which the 49ers did not recover.

The linebacking core was quite impressive. Julian Peterson and Derek Smith were making plays left right and center. Jamie Winborn and Jeff Ulbrich were not that far behind. This group is blazing fast across the board. Saleem Rasheed was again in the game for many snaps. He’s very quick, and had a more solid performance than last week. Clearly he is adjusting to the speed of the game. Frank Strong is making a real bid for the sixth linebacker position. Strong had a sack, and kept pressure on the quarterback on the blitz. He was also good in stuffing the run and in coverage. Kawaguchi did not appear to log any play time other than on special teams.
