SANTA CLARA, Calif. -- He has a voice that has been described as both piercing and maniacal. He carries the nickname "Lord" from when he was an assistant at Stanford. He leaves messages on his voicemail at the office just before he falls asleep or if he wakes up in the middle of the night with a thought.
Vic Fangio is coordinator of the San Francisco 49ers' defense, which was the NFL's third best during the regular season and is the best of the four remaining teams in Sunday's conference championship games. The 49ers play the Falcons in Atlanta for the NFC title.

It may take a genius to stop a Falcons offense led by quarterback Matt Ryan that has the sixth-best passing offense and eighth-best overall offense.
More accurately, it will take Fangio's schemes, as utilized by linebacker Aldon Smith -- who was second in the league with 191/2 sacks (one behind Houston's J.J. Watt) -- All-Pro linebacker Patrick Willis and defensive tackle Justin Smith.
Atlanta has excellent receivers in Tony Gonzalez and Julio Jones and fine running backs in Michael Turner and Jaquizz Rodgers. It's a combination the 49ers haven't faced, even against the Seahawks, Giants or Patriots.
"We can't create big seams," Fangio said. "You give backs big seams and then a good back becomes a great back and a great back becomes unstoppable.
"It all starts before the tackle is even attempted. You've got to establish the line of scrimmage and not give them big alleys and holes to run through."
Defense wins, they say, because if the other team doesn't score, the worst your team will have is a 0-0 tie. In three of the 49ers' last four games, however, they've had a 45-31 win over the Packers, a 42-13 loss to the Seahawks and a 41-34 win over the Patriots. They haven't come close to keeping the opponent from scoring. And scoring and scoring, for that matter.
"In playoff football," strong safety Donte Whitner said, "you're facing really good quarterbacks who know how to make adjustments. In the end, you've just got to make more stops than their defense does."
Aldon Smith didn't have a sack against the Packers. "It's just that they were throwing it fast," Fangio said. "He's rushing good. I think teams respect our rush. They throw it quick sometimes. It's not always stats. Don't look at the play-by-play after the game and make your conclusions. Watch the game."
Willis said to the Huffington Post two months ago: "We have one heartbeat. No person is bigger than the other. If we play together, we believe good things will happen."
Justin Smith was injured against New England on Dec. 16 and missed the last two regular- season games. Despite one doctor's prediction that Smith wouldn't play again until next season, he returned last weekend against the Packers. "He and Aldon played well," Fangio said.
Harbaugh, very much enamored of Smith's toughness and work habits, said: "The legend grows. What a player."
Willis will have a difficult assignment: covering Gonzalez.
"He's improved," Fangio said of Willis' pass defense. "He's proven he can do it on a consistent basis. Some weeks are tougher than others. Obviously, this week is a very tough week."
And for the 49ers, once again one win from the Super Bowl, a very important one.
Crabtree, police meet
49ers wide receiver Michael Crabtree has voluntarily met with police in their investigation into an alleged sexual assault in a hotel, his attorney said Saturday. The 49ers said he made the trip to Atlanta.
Police had said they were investigating a sexual assault allegation involving Crabtree in a San Francisco hotel early last Sunday. Crabtree hasn't been detained or arrested. -- AP
