SAN FRANCISCO — Saturday's game started like a dream for Colin Kaepernick — the sort of dream that wakes you up in a sweaty panic in the middle of the night.
Just minutes into the action, on a second-and-6 play from his own 47-yard line, Kaepernick telegraphed a throw off his back foot to tight end Vernon Davis, who was double covered. Green Bay's Sam Shields stepped in front of the pass, caught it with ease and took off toward the end zone. Kaepernick dove for Shields' legs but came up short, and just like that the Packers were up 7-0.
The crowd was stunned. The Packers were amped. And Kaepernick, making his first NFL postseason start, might easily have been wrecked.
He wasn't. The second-year quarterback took a deep breath, coolly trotted back onto the field a moment later, and proceeded to direct a stunning 45-31 victory over the Green Bay Packers at Candlestick Park.
"After that unfortunate interception, I wanted to see what his body language was," center Jonathan Goodwin said. "It was good. He came out confident, took control of the huddle. Led us right down the field for a touchdown."
Indeed, Kaepernick followed the interception by leading the 49ers 80 yards to an answering score, finishing the drive himself with a 20-yard sprint to the end zone.
It was a preview of the rest of the game. Kaepernick would complete 17 of 31 passes for 263 yards and two touchdowns to Michael Crabtree. But he did his best work trampling the Packers with his feet. Kaepernick ran for 181 yards, an NFL record for quarterbacks, postseason or otherwise.
"He was running all over the field," Packers quarterback Aaron Rodgers said. "He's big, strong, athletic, throws the ball well and runs the ball extremely well. We didn't really have an answer for him."
Niners offensive coordinator Greg Roman ran a heavy dose of the Pistol offense — similar to the one Kaepernick ran in college at Nevada. It usually came from a diamond formation, with three teammates around Kaepernick in the backfield, one at each side and one behind him. Frequently, one of those backfield mates was a tight end, who motioned toward the line and provided extra protection.
Kaepernick would then run the read-option, and when he kept the ball, the results were electric. Roman dialed up routes that cleared the middle of the field; much of Kaepernick's yardage came on scrambles up the middle.
