Remembering back to the game on Sunday, there was one thing that I remember being an absolute life saver for us. While the 49ers were already down, the Broncos ran a flea-flicker that if it weren't for a penalty flag, would have been the nail in the coffin for the 49ers and we would have gone on to lose that game. But this brought up a question that I have about the 49ers defense this year. Why are we so bad when it comes to flea-flickers, screens, and play-actions?

Those plays are designed to hurt an aggressive defense and from what I have seen out of our defense this year, we have not been an aggressive defense. We aren't sending all kinds of different blitzes at the QB, we aren't getting a large amount of sacks and our defense does a pretty good job at containment (especially when it comes to another trick play, the reverse). So why have these plays been so effective? Is it because of the play-calling? Is it the fault of the DB's and Safety's being too aggressive and biting on plays? And what do you think should be done to fix it. Whenever we get hit with a 2nd or 3rd flea-flicker in a season and it continues to work, something is very wrong.
