SAN FRANCISCO — Colin Kaepernick no longer qualifies as a secret. The 49ers’ backup quarterback had 65 rushing yards and a touchdown run coming into the Bills game, and had started to draw a lot of attention for his versatility in the Wildcat formation.
But every week the Niners seem to find new assignments for the second-year pro. Kaepernick carried the ball four times for 39 yards in Sunday’s 45-3 victory, including a 16-yard touchdown run and a 15-yard scamper that set up Frank Gore’s scoring plunge. Kaepernick also completed his first pass of the season, a 7-yarder to Kyle Williams.
He played close to 20 snaps total, lining up under center, in shotgun formation and even as a wide receiver a few times.
“You never want a defense to know what you’re going to do,” Kaepernick said. “Our coaches do an amazing job of game-planning, and I’ll leave that up to them.”
The only 49er who conceivably might be disturbed by Kaepernick’s progress is Alex Smith, the starting quarterback, but Smith insists that isn’t the case.
“I think it’s a great thing,” he said. “I mean, it’s another thing that the defense is going to have to prepare for. ... You only have so many reps during the week to get ready. The more they have to think about, the better.”
No rest for the winners
The 49ers have won consecutive games in convincing fashion, but next week’s assignment promises to be tougher: a rematch with the New York Giants, the team that denied the Niners a Super Bowl appearance with a 20-17 overtime victory in last year’s NFC championship game at Candlestick Park.
“We’re back home, back at our house,” tight end Vernon Davis. “We’re gonna approach this week of practice with a will-to-win attitude. ... We can’t take it easy on these guys, because we know what they can do.”
