That 3rd and 13 was completed for a first down and called back due to PI on Witten which had no bearing to the completion. I'd say that was a good play call. Oh, and the 3rd and 13 was set up by a poor run and then a fumble. Not bad coaching, rather poor execution.
What I'm arguing is that the play calling is not the main reason we lost, as there were plays to be made out there due to the playcalling, and the plays were not made by the players.
When you fumble the ball after a huge completion, miss a mental assignment on your QB's blind side and he fumbles, and drop perfectly placed, drive-sustaining passes, that is not on the OC.
Green Bay has one of the best defenses in the league. When playing good defenses you're not going to have as many opportunities to make plays as you would against a weaker team. Therefore, when opportunities DO arise, players need to take advantage of them when they are in positions to succeed.
They did not, and ultimately it lost them the game far more than "bad coaching"
