I look at the Cardinals game as an anomaly. The refs were not calling the game evenly. If the offsides call on the FG didn't demonstrate what I am saying then there is nothing else I can say. I understand that penalty in the long run probably didn't matter, but it does indicate the refs were looking too hard for reasons to throw flags against Dallas in the first half. Then later, the picked up flag in the end zone, which was clearly a penalty by the official rules, demonstrates the point even more. I do no think every crew will call the game that way, but we know now there are at least 2 crews that will, Hochuli being the other.
In reality, the Cowboys gained more yards than Arizona and 185 of them on the ground. That should be enough to win every game. The penalties hurt but the penalties in the end zone that were not called Hurt even more.
