San Francisco placekicker Phil Dawson leads the NFL in scoring the past two weeks. That is not necessarily a good thing for the 49ers.

Dawson kicked five field goals, including a pair from more than 50 yards, to account for a majority of the 49ers’ scoring Sunday in a 22-17 home win over the Kansas City Chiefs.

The five-kick day came on the heels of Dawson’s four field goals the previous week in a 26-21 victory over the Philadelphia Eagles.

“He stood up there and knocked them down like a Hall of Famer,” 49ers coach Jim Harbaugh said after the win over the Chiefs. “I feel awesome for Phil. He can stand in front of the mirror and say, ‘I’m Phil Dawson. I’m a football player.'”

Unfortunately for the 49ers, they have an offensive unit that must stand in front of a mirror and admit it is having trouble in the red zone. Quarterback Colin Kaepernick & Co. penetrated the Kansas City 20-yard line four times Sunday but got into the end zone just once.

In the past two weeks, the 49ers finished off just three of their 12 scoring drives with touchdowns. Dawson provided the points the other nine times.

As a result, the 49ers are down to 25th in the league in red-zone efficiency at 44.4 percent. That is 11 spots lower than last season, when they converted 53 percent of their drives inside the opponent’s 20 into touchdowns.

“We’ve got to do better at that,” veteran offensive tackle Joe Staley said. “We’re definitely not coming away with enough touchdowns. It’s definitely something we will improve on. We have to.”

The nine-field-goal fortnight is a first for Dawson. The veteran’s positive results overshadowed an offense that did not score a fourth-quarter touchdown either of the last two weeks — and doesn’t have any in the final 15 minutes all season.

“As long as we win,” Kaepernick said, “that’s all that matters.”

REPORT CARD VS. CHIEFS

PASSING OFFENSE: B-minus — QB Colin Kaepernick didn’t throw an interception and made good use of his third (Stevie Johnson) and fourth (Brandon Lloyd) receivers in providing just enough offense to allow the 49ers to win. Failures in the red zone, where the 49ers scored touchdowns on just one of four entries, keep the grade from being higher.

RUSHING OFFENSE: B-plus — The 49ers successfully kept the Kansas City offense off the field (the Chiefs ran only 50 plays) by using ball control. It remains a successful formula in the Jim Harbaugh era. When RB Frank Gore runs well (he had 107 yards), the 49ers usually win (they are 13-0 under Harbaugh when Gore tops 100). The running game did not get into the end zone, however.

PASS DEFENSE: B — Holding QB Alex Smith to 175 yards is nothing special. However, in a game that came down to the Chiefs’ final possession, the 49ers for the second week in a row got a key interception (both times by CB Perrish Cox) to turn a tense finish into a win. Smith had two touchdown passes, but none in the final 26:56 with the game on the line.

RUSH DEFENSE: A — The stat sheet shows RB Jamaal Charles with a respectable 80 yards on 15 carries, but the 49ers turned him into pretty much of a nonfactor, keeping him out of the end zone. The 49ers made the Chiefs attempt to win the game on the arm of Smith, and that is exactly what San Francisco hoped to do.

SPECIAL TEAMS: A — The game will be remembered by many as one in which the 49ers benefitted from a gutsy fake-punt play in their own territory. But truth be told: The game was won for the second week in a row on the foot of PK Phil Dawson, who made five field goals, two of them from more than 50 yards. Dawson scored 16 of the 49ers’ 22 points.

COACHING: C — Good teams from the NFC are supposed to beat mediocre teams from the AFC at home, so there was nothing unexpected about the 49ers’ five-point win. San Francisco improved on penalties (committing just two for 10 yards) but once again couldn’t find the right plays to get into the end zone more than once despite four trips into the red zone.
