SANTA CLARA — As the 49ers' offensive struggles linger, it seems more and more as if the familiar refrain becomes: What's wrong with Colin Kaepernick?
Nothing is amiss with the 49ers quarterback, coach Jim Harbaugh said Thursday.
"He's doing a heck of a job," Harbaugh said. "I would be puzzled why people would think that. What's more important is what we see."
What people from the outside see is the 49ers last in passing and Kaepernick's stats significantly less impressive than last season.
Through 10 games, Kaepernick completed 56.2 percent of his passes, with 11 touchdowns and seven interceptions, for an 81.8 passer rating.
He finished the 2012 season as the 49ers starting quarterback after he replaced Alex Smith nine games in — Smith suffered a concussion, and he spent the rest of the season on the sideline.
During his 13 games last season, seven of which came as the starter, Kaepernick completed 62.4 percent of his passes, with 10 touchdowns and three interceptions, good for a robust 98.3 passer rating.
Harbaugh praised Kaepernick for his "laser-like focus" before certain games late last season, in particular the postseason.
That hasn't changed one bit this season, Harbaugh said.
"It's been consistently good," Harbaugh said. "He's been like that every week."
Kaepernick also is exemplary in taking charge and playing a prominent role in helping the 49ers emerge from their uneven play.
"Colin's always been A-plus in that kind of way," Harbaugh said.
The 49ers are fifth in rushing offense. However, they are last in passing at an average of 168 yards per game. The Raiders are second-to-last at 186.4. Last season, the 49ers ranked 23rd at 206.1.
Yet, Harbaugh hasn't wavered in his support of Kaepernick. And he certainly isn't listening to those from the outside wanting to know what's wrong with his franchise quarterback.
