SAN FRANCISCO -- The 49ers outscored their previous two opponents by a combined 79-3, but Giants safety Antrel Rolle said he still felt supremely confident entering Sunday's game.
"We liked the matchups," he said. "A team that put up 79 points the last two games, you have to be careful because they throw a lot of different things at you, but we just played the system, trusted the man beside us and were able to make plays."

Rolle made two of the biggest, picking off Alex Smith twice in the third quarter in setting the defensive tone in the Giants' 26-3 win at Candlestick Park.
Rolle's first interception came with 10:07 left in the quarter when he picked off a pass intended for former Giants wide receiver Mario Manningham.
"We were in a cover-3 and I was able to able to read the quarterback," Rolle said. "The cornerbacks did a great job on the route, and I was fortunate enough to hold on with one hand and make a play."
Rolle got the Giants to the 49ers' 12-yard line, and they settled for a 30-yard field goal by Lawrence Tynes to make it 20-3.
Rolle struck again on the next series, picking off a pass intended for Michael Crabtree at the 49ers' 27. Rolle ran it back to the 49ers' 5, and the Giants again couldn't punch it in, settling for Tynes' 22-yard field goal to make it 23-3.
"Ahmad Bradshaw screamed from the sidelines, ' 'Trel, [Smith] is watching you!' " Rolle said. "So if he's watching me, I'm going to go 'sugar' him and make like I'm playing a deep third [of the field]. I came down and the ball came right to me."
Smith threw a season-high three interceptions -- Prince Amukamara had the other in the first half -- as the Giants completely throttled a 49ers offense that had been one of the most dominant in recent weeks.
"I could tell at times we had him a little rattled," Rolle said of Smith.
"But every quarterback is going to get rattled sometimes, depending on how you disguise your coverage, things of that nature. I think the guys up front did an exceptional job, and I think on the back end, we held our own pretty good."
Rolle called this "our most complete game all year long against a very worthy opponent. We're just continuing to grow. We're fortunate, and we're looking forward to next week."
