Jim Harbaugh has the 49ers in first place in the NFC West
The San Francisco 49ers took a two-game lead in the NFC West with tonight's victory on Monday Night Football. There are areas where the 49ers can still improve and become more consistent.
The offensive line allowed four sacks in a game where the 49ers passed the ball sparingly.
The 49ers also committed too many penalties on offense, especially in the first half. An Alex Boone face-mask penalty killed the 49ers' promising opening drive.
The 49ers seemed to have trouble early in the game getting the play in to quarterback Alex Smith. They were called for a delay-of-game penalty once and forced to burn a timeout on another play to avoid another penalty.
Garrett Celek, was called for a holding penalty on the 49ers' second drive that nullified a good offensive play. A false start on Mike Iupati also put the 49ers in a long-yardage situation, which enabled Arizona to blitz on the next play and sack Alex Smith.
A 15-yard penalty against 49ers' gunner C.J. Spillman also cost the 49ers a chance to pin Arizona deep in their own territory.
Aldon Smith was victimized in pass coverage. He had trouble in pass coverage earlier this year and needs to strengthen that part of his game.
After the 49ers went up 24-0, they got very conservative on offense and just bled the clock. It was a very solid win and the 49ers should be credited for playing a good game.
However, the 49ers must clean up these mistakes, as they will not be able to overcome them against the top teams in the league. Injuries have decimated the Arizona offensive line, which enabled the 49ers defense to dominate the line of scrimmage.
