ATLANTA -- The San Francisco 49ers entered the NFC Championship Game having allowed at least 31 points to three of their previous four opponents.It's looking like that trend will continue after Atlanta jumped to a 24-14 halftime lead over the 49ers in the Georgia Dome.This one has been pretty easy to analyze. The 49ers' four-man pass-rushes aren't affecting Falcons quarterback Matt Ryan. Five-man rushes aren't working, either. As a result, Ryan has completed 18 of 24 passes (74 percent) for 271 yards and three touchdowns in the first half.
