This season's defensive performance was really marked by the stark difference between weeks 1-6 and 7-17. It was almost as if two different units were out there. In the first six weeks of the season every opponent cracked 400 yards of offense and 300 yards passing. Since then only the Pittsburgh Steelers have surpassed 400 yards of total offense and no QB has passed for over 300 yards. Through week 6 the defense allowed 152 points (25.3 per game). Since then the D has allowed 123 points (12.3 per game). Therefore it makes sense to take two looks at the defensive performance this season.
