SAN FRANCISCO —
Kaepernick, Aldon Smith and Hunter sure made general manager Trent Baalke look good for his selections from the 2011 draft class.
And reigning NFL Coach of the Year Jim Harbaugh earned a key victory four days after his own health issue. The 48-year-old Harbaugh underwent a minor procedure for an irregular heartbeat Thursday.
The 49ers added a safety in the fourth quarter after a replay review. With 9:24 left, former San Francisco offensive lineman Chilo Rachal was called for intentional grounding out of the end zone, but Harbaugh challenged and the review showed Rachal’s knee was down in the end zone before the ball left.
“It definitely wasn’t our best effort, by no means,” Campbell said.
The soft-spoken, stone-faced Kaepernick went 16 for 23 with a 133.1 passer rating. He completed 12 of his first 14 passes with a 57-yard strike to Kyle Williams that set up Davis’ 3-yard TD on the next play — and he already had amassed 126 yards passing by the end of the first quarter.
The 49ers led 17-0 on Hunter’s early TD run in the second, quickly topping the 14.8 points the Bears were allowing per game.
Kaepernick threw for 184 yards in the first half alone — an impressive outing for the second-year pro selected in the second round out of Nevada.
“I think after the first drive I felt really comfortable with what they were doing and what we had in our game plan,” he said. “I really wasn’t too nervous. I’ve had a lot of time in this offense. My teammates were really supportive.”
Frank Gore ran for 78 yards and David Akers kicked field goals of 32, 37 and 32 yards for the 49ers, eager to defend their home field a week after settling for a frustrating 24-24 tie against the division rival St. Louis Rams.
They outgained Chicago 249-35 in a lopsided first half.
