SANTA CLARA -- Quarterback Colin Kaepernick has not spent any more time preparing for the New England Patriots' defense, he said Wednesday.
Kaepernick said he has maintained the same preparation schedule since the beginning of the season, beginning when he was Alex Smith's backup.
Kaepernick faces his biggest challenge Sunday night in his fifth NFL start, as he goes against a Patriots defense that figures to come up with a few new wrinkles in hopes of confusing the second-year player.
"They give you a lot of different looks on defense," Kaepernick said. "You just have to be prepared for it. You have to be ready for their disguises and different coverages, different fronts they're going to give you."
"It'll be a great challenge. It's a great opportunity to show what we're capable of."
The 49ers have averaged 25.8 points in Kaepernick's four starts, including two touchdowns from the defense. New England features the league's No. 1 offense and averages 36.3 points per game. The 49ers might have to unleash a more prolific offensive attack in order to stay close.
There is plenty Kaepernick can learn from New England quarterback Tom Brady, who has thrown 29 touchdowns and just four interceptions.
"What he does mentally," Kaepernick said. "He knows exactly what he wants to do against every look a defense is going to give him."
Kaepernick struggled Sunday against the Miami Dolphins in getting the offense to the line of scrimmage and going through his pre-snap reads. The 49ers wasted four timeouts on offense.
"We just have to practice it," said Kaepernick, who said he did not know why the 49ers struggled in that aspect of the game.
He will need to break the huddle in a timely fashion to properly diagnose the Patriots' defense, he said.
"Trying to see what the defense is trying to do pre-snap," he said. "They give you a lot of different looks, a lot of different fronts. We just have to be ready for it."

--Kaepernick said Alex Smith has been a help to him as the team's backup quarterback.
"He's been great," Kaepernick said. "He's helped me with everything I've asked. Even on the sideline he's going over looks with me and making sure I'm seeing everything."
--Kaepernick has built a rapport with veteran wide receiver Randy Moss.
"He's a true professional," Kaepernick said. "He's going to do whatever it takes to make sure he's ready to play on Sunday.
"Randy is a great guy. He's a great teammate. He's someone that everybody should try to be like, as far as in the locker room and how they are as a teammate. . . Randy has always been great. He's always going to tell me what he's seeing with the defense. We have a good relationship."
--Kaepernick on why he's comfortable throwing to Michael Crabtree: "He's open. So you're going to throw the ball to the guy who's open."
