Defenses shining through first half in Baltimore

Hopefully you had a tasty Thanksgiving and have settled on the couch for some football.

We’ve got a good one here in Baltimore, as the Ravens lead the 49ers 6-3 at halftime. It was billed as a defensive matchup, and through two quarters that’s pretty much where we’re at.

Dan Kolko will have some first-half notes on the Ravens, but for the visiting 49ers, they are playing as advertised. Defensively, they’ve held tough against a versatile Ravens offense. The Ravens have just 46 yards on the ground and failed to capitalize on a first and goal scoring chance late in the second quarter, while quarterback Joe Flacco has been held to 69 yards on just five completions. In fact, with the exception of a costly pass interference call that gave Baltimore the ball inside the San Francisco red zone, the 49ers defense is playing very well.

On the offense things could be better. Quarterback Alex Smith is a solid eight of 12 for 70 yards, but hasn’t really tested the Baltimore secondary with any deep throws and threw an interception in the waning seconds of the half to Lardarius Webb, nullifying a likely field goal attempt. The numbers aren’t bountiful, but Smith has been under constant pressure all night. He’s been sacked four times and hurried countless others, but so far has only the one mistake with the interception.

Frank Gore has just nine carries for 21 yards, but Smith has found four different receivers in the passing game, with tight end Vernon Davis leading the way with 29 yards on three catches.

San Francisco will get the ball to start the second half. Obviously one touchdown puts the 49ers in front, but at the rate this offense is moving the ball against the Ravens defense, that end zone is a long way away.
