Using an objective way, instead of the dumb old "points allowed" method to calculate the better defense, I used adjusted averages to figure out which team's defense is better. Now, taking away the Patriots and Steelers from their opponents' statistics, here are their opponents averages when not playing the two teams. Here are my conclusions. Steelers opponents have scored 1520 points in 72 games, for an average of 21.1 points per game. The Steelers have allowed 14 ppg this season. The Steelers adjusted defensive differential is -7.1 ppg, so their defense is 7.1 points better than the average team against the same opponents. Patriots opponents have scored 1755 points in 72 games, for an average of 24.4 points per game. The Patriots have allowed 16.3 ppg this season. The Patriots adjusted defensive differential is -8.1 ppg, so their defense is 8.1 points better than the average team against the same opponents. The Patriots have shut down much tougher offenses, including Indianapolis and Dallas. While no mainstream pundit will bother to use this reasonable formula and will proclaim the Steelers the "#1 ranked defense" just remember that the truth lies here. Steelers fans are in for a rude awakening when they come to the Razor thinking they have an edge on defense. One more note of interest. On third down, the Pats' defense leads the league, allowing a first down only 30.3% of the time. The Steelers rank 13th, allowing a first down 41% of the time.
