I don't think the defense played all that bad. Yes, they allowed drives to continue and didn't get off the field in short order. However, they kept the home team from the endzone until a fumble at about their own 20. I believe this game would have been totally different had the 2 first half INTs not been thrown. For the first 3 quarters, 3 turnovers and only 13 points allowed in a road game isn't all that bad. You have to go to the source, and that was the turnovers. Had the offense converted some of those drives that resulted in turnovers into points, the pressure would have been on the 49ers and Smith ... and they
would have been prone to turn the ball over. A team that only scores 3 points in the NFL is going to lose, then add in 4 turnovers ... sounds like a problem with the offense to me.
