It has been questioned why this Packers defense has not performed as well this season, and after watching this game, I find that the defensive line seems to be the main problem despite the Packers' pass defense woes.
In a stark contrast from last year, the Packers have not been able to rush the passer well at all, as their defensive line has commonly gotten swallowed up by their opponent. This could be contributed to the loss of Cullen Jenkins, as the Packers have failed to find an adequte replacement to Jenkins so far this year, and because of this, have not been able to get the same pressure on the quarterback.
Because of this, the quarterback is getting more time to make throws and make better decisions, and the running game is much more effective for the opponent. This was apparent both this week against the Bears and last week against the Chiefs.
While there are certainly problems in the secondary, they at least are making big plays on the ball, as they create frequent turnovers. This defensive line, however, just hasn't been pressuring the quarterback enough this year.
If I were Ted Thompson, I would focus my energy on finding a longterm replacement for Cullen Jenkins that can make a quick impact. If he can do that, I guarantee this defense will be back to its dominant ways of 2010.
