Just to be the Devil's advocate here I will argue differently. Green Bay's defense was gassed, they needed some recovery time. Green Bay's offensive line had started to wear down and Aaron was getting pressured. Dallas was teeing off with a pass rush because the Packers were showing little else. There was a lot of time on the clock, a quick strike score was going to be a problem if Dallas had a lot of time left. Tired O-linemen sometimes hold on pass plays which moves teams back and stops the clock, an unacceptable result. The Packers had shown a few very nice rushes in the game. Calling a play similar to Ty's great run against Chicago was not a bad call. It was not settling for the field goal at that time, it was an attempt to catch Dallas a bit off guard, run a bit of clock, improve worse case outcomes for a filed goal if it had to be kicked, but was really just an attempt to keep the drive going. Aaron cannot throw literally every play. That is not good strategy even when they have Jordy and Bulaga isn't gimpy. The problem was not the play call, it was the piss poor execution. But for the Cowboy slicing through unblocked it is a good call. Maybe time to ask what would have happened had the same player sliced through on a pass call. Maybe a sack for even more lost yardage, maybe a strip sack which we nearly saw on the next drive from a much smaller defender.
The call was fine, the execution sucked. The Packers went in to Dallas without their two best corners, without their best W.R., without their best R.B., with one of their best L.B.'s playing with a club on his hand and they came away, fortuitously, with a victory. How?, unreal Q.B. play and great coaching. The Packers won the game because they have higher football I.Q. than the Cowboys. The Packers had less mental errors though more physical ones, which is to be expected with the injuries. Had the Cowboys not pissed away their T.O.'s in the first half they would have had a great opportunity for a late filed goal. Had they not committed a 15 yard penalty by illegal substitution maybe they help themselves. Had they not celebrated, like idiots, after a small positive defensive stop maybe they would not have been late substituting allowing Aaron to do what he does.
