Towards the end of the third quarter the Cardinals had the ball and would have obviously drove down the field and scored to make it a one score ball game going into the fourth quarter.  Unfortunately, Kolb completely screwed up and committed an intentional grounding penalty in the end zone resulting in a safety and putting the Steelers up 26-14.  I had to go back and look at my dvr to see how Woodley got into the backfield so quickly.  What I saw was telling...many of you may have noticed this also.

Despite the Steelers sending only four rushers our O-line decided that it would be best to only block three of them and leave Woodley unblocked to the quarterback.  Brandon Keith makes a horrible judgement call in taking the guy to his left rather than blocking Woodley.

Bad coaching? Unfortunate circumstance?  I'm sure I could find many more examples but this one stood out.  Russ Grimm may be a hall of famer but it doesn't mean that he can coach worth a damn.
