OK, this thread has had some posts similar to comments made in Chat during and after the game.
Here is my opinion on coaching and team success.
1) It is incredibly stupid to blame every failure on offense and every failure on defense to the respective coordinators or the head coach. Sometimes players get out-played. Sometimes they make mistakes.
2) It is, on the other hand, reasonable to question or blame coaching when results are below expected standards over several games and especially several seasons. However, even this questioning and blaming should be able to point to particular issues that repeat.
3) It is, at least, understandable to question coaching when the other team defeats you on either offense or defense by alignment, especially in successive plays.
4) My reaction to the game: It was a team loss. The Defense played well enough that if the offense played close to the level we've come to expect, we should have won. To that extent, I agree the loss is probably more on our offense. However, it seemed to me that in the last drive of the first half (8+ yds/play), and the last drive of the game (10+ yds/play), our D was not playing as aggressively as it had when we were being successful. I did not see the same change in Offensive play calling.
Take it for what it's worth.
