SAN DIEGO -- The Ravens are trailing 17-7 at halftime because they can't get to Philip Rivers.
The lack of a pass rush from the Ravens -- who lead the NFL in sacks -- has let Rivers pick apart the secondary. Rivers has completed 11 of 15 passes for 170 yards in the first half. Baltimore, which ranks fourth in the NFL against the pass, gives up an average of 192 yards passing per game (Rivers is only 22 yards off that mark in one half).
Rivers has completed a 58-yard pass to Vincent Jackson, a 20-yarder to Antonio Gates and a 19-yarder to Malcom Floyd. He has guided the Chargers on scoring drives of 74, 53 and 80 yards against the Ravens.
Meanwhile, Ravens quarterback Joe Flacco has been streaky throughout the first two quarters. He is 8 of 15 for 102 yards in the first half. His best pass was throwing a 15-yard touchdown pass in between two defenders to tight end Ed Dickson, which tied the game at 7 in the second half.
This marked the first time the Ravens trailed at halftime since Nov. 13, which was also their last West Coast trip. Baltimore faced a 19-7 deficit at Seattle.
Billy Cundiff sliced a 36-yard field goal wide right to end Ravens' opening drive. Cundiff, who didn't practice all week with an injured left calf, is 2 of 5 in December.
The Ravens haven't looked like themselves at all on defense. Baltimore allowed a 12-play, 74-yard touchdown drive to the Chargers. It ended the Ravens' 21-game streak of not allowing a touchdown on their opponents' opening drive.
