Here is a halftime update on the action in San Diego where the Chargers lead the Raiders, 27-7:
What are the odds of the Broncos sitting in Denver watching game and wondering how they were beaten by three touchdowns at home by Oakland just 11 days ago?
The Raiders are having their worst performance of the season, perhaps worse than opening day against Denver or a few weeks ago against Atlanta. This team looks terrible -- just terrible.
Oakland quarterback JaMarcus Russell was taken to the locker room on a cart before the half. That is never a good sign. Tight end Zach Miller, tackle Robert Gallery and defensive tackle Tommy Kelly were also banged up.
The Chargers are taking their frustrations out on Oakland. San Diego, which is playing its best game in a bad season, tried to score a touchdown in the final second of the first half and settled for a field goal.
Vincent Jackson did the impossible in the first quarter. The San Diego receiver smoked Oakland star cornerback Nnamdi Asomugha badly on a deep ball. Teams rarely go after Asomugha, but Philip Rivers did and it paid off. Asomugha was beat so bad he had to interfere with Jackson, who still caught the ball. Jackson is continuing his trend of having big performances in prime-time games.
The Raiders have not scored a touchdown in the first quarter all season.
The Raiders also continue to struggle with discipline issues. Two personal fouls hurt the team in the first quarter.
The Chargers' offensive line looks much better than it did Sunday against Atlanta. Guard Kris Dielman is back and is playing well. He didn't play against the Falcons because he had the flu.
San Diego safety Eric Weddle is having a nice game. He is always around the ball.
Wonder if the Raiders are looking any better in 3-D? Probably not.
