 Playing defense and protecting the football are what they do best, and that formula led to a 20-13 victory over the Houston Texans on Sunday, putting Baltimore in the AFC title game against the New England Patriots. "I always say there is a right way to do things, there is a wrong way to do things and there is just the Ravens' way of doing things," linebacker Terrell Suggs said. But Baltimore wasn't penalized once, didn't commit a turnover, intercepted rookie quarterback T.J. Yates three times and totaled four takeaways _ two in the first quarter and two over the final eight minutes. They will play the Giants next Sunday at Candlestick Park after New York defeated the defending Super Bowl champion Green Bay Packers 37-20 on Sunday. We don't try and do anything too fancy, although we do have our changeups here and there. That's what a team is and I think we have a great one here." "His big plays always seem to happen when you need one." Goldson had six interceptions for the NFC West champions during the regular season, then his biggest yet Saturday. They forced five more Saturday, and only had one turnover themselves. "If we don't turn the ball over like that, we have a chance to win. They gave us no chance," Goldson said. If I'd done a better job of protecting the football, I really think we'd have come out with the win today. "I had figured coming into this game they would feel like, `Let's keep everything in front of us, let's not give up big plays and obviously do a good job against the rush and try to put them in third-and-long situations,'" Brees said. "I told myself that I was going to hit anything moving today and that I was going to be extremely physical, even if I hit my own guys," he said. ... To come out and play the way this team has played, I think it's just remarkable," McNair said. "We wanted to come out and play our style of football, which is playing physical, being a great tackling team, and playing with good fundamentals which has carried us all year," Fangio said. I know the special teams contributed to that as well. We ignored everything and focused on us and what we had to do to come win this game." "You have to do whatever you have to do to win a football game," Ravens coach John Harbaugh said. ... With the Ravens' home win, it's the first time since the NFL went to current playoff format in 1990 that the first seven games have been won by the home team.
– For Eli Manning and the New York Giants, Lambeau Field has become a familiar launching pad. After beating the Green Bay Packers at home for the second time in four years, they only hope this trip ends the same way—at the Super Bowl. Manning threw three touchdown passes and the Giants shocked the Packers 37-20 in an NFC divisional playoff game today. Manning threw for 330 yards, sending the Giants to San Francisco for the NFC championship game next Sunday night. More from today's football games: The San Francisco 49ers beat the New Orleans Saints in a thrilling 36-32 game today. With New Orleans poised to score on its opening possession, Donte Whitner delivered a crushing blow that knocked out running back Pierre Thomas and forced the first of five Saints turnovers. San Francisco's hard-hitting, opportunistic defense set the tone the same way it has all season, putting the 49ers back in the NFC championship for the first time since the 1997 season. If style points and offensive fireworks meant anything, the Baltimore Ravens wouldn't stand a chance of making it to the AFC championship. Playing defense and protecting the football are what they do best, and that formula led to a 20-13 victory over the Houston Texans today, putting Baltimore in the AFC title game against the New England Patriots next Sunday, with the winner advancing to the Super Bowl in Indianapolis on Feb. 5.
