...was about as one-sided a game as I have ever seen. The only reason that the winning margin was not at least 7 points bigger was that the Saints kneeled down and turned the ball over after arriving at the Cowboys 5 yard line with 3 minutes left. I thought that was a good piece of sportsmanship by the Saints to avoid running up the score unnecessarily, since they had shown that they could score at will against the Cowboys defense.
The most interesting part of the game was watching Bill Parcells' body language in the second half. Instead of ranting and raging at the incompetence of the Cowboys, both on offense and defense, Parcells was standing on the sideline with his arms folded and his lips pursed, as if deep in contemplation, saying little on his headset. My take is that he was struggling to cope with the public display of the Cowboys' weaknesses, knowing that all future opponents would be watching the game film from Monday onwards. Most likely he was already thinking about what can possibly be done to reduce those weaknesses. Certainly, without some changes, I do not see the Cowboys advancing deep into the playoffs. They appear to be a second-tier playoff team right now.
At this point in the season, this is my team assessment:

Top Tier
========
Chargers
Bears

Second Tier
===========
Ravens
Bengals
Colts
Seahawks
Cowboys
Patriots

Third Tier
==========
Giants
Jaguars
