Yeah 33 points scored by the offense for the highest offensive score of the season is really tough to take.
I get what you're saying and I'm not trying to be an alarmist, but consider a few things.
The 49ers are allowing an average of 31 points in their 6 other games. So at home, the Packer barely topped what they've allowed on balance. And that was considering that twice they got the ball in SF's territory due to fumbles.
33 points, a season high for Green Bay, only tops the Rams' point total once this year.
And lastly, and this is my main point, the offense has been out of sync. I think most people have been able to observe that when watching the games. It hasn't locked in yet. I'm hopeful that it will at some point, but if it doesn't this week, they're going to lose.
