"I don't look at it as a drought," Fangio said Thursday. "You guys were at the game last week. The guy (Packers quarterback Aaron Rodgers) was throwing the ball extremely fast."

In their next game, the second-seeded 49ers (12-4-1) will visit the top-seeded Atlanta Falcons (14-3) at noon Sunday for the right to reach Super Bowl XLVII.
The 49ers are seeking their sixth Super Bowl title, and their first road playoff win since claiming a Super Bowl berth Jan. 8, 1989 at Chicago. The Falcons have reached the Super Bowl only once, when their 1998 team fell 34-19 to the Denver Broncos.
In Saturday's 45-31 win over the Green Bay Packers, the 49ers welcomed Justin Smith back from a two-game absence related to a torn triceps tendon. Fangio said Smith and Aldon Smith teamed up well on the right side of the line in their reunion, noting: "They played well and did a good job for us."
