Updated adjusted point differential. The league average for points allowed this season is 21.4 points per game. Patriots opponents, when not playing the Patriots, have allowed 24.3 points per game. The Patriots are averaging 39.9 points per game, which is 15.6 points above average. Again, the reason why these defenses are ranked around the worst in the league is simple: their points allowed has greatly increased as a result of playing the Patriots. The bottom line is, when someone is listing the teams they've played and saying 30th ranked, 29th ranked, etc. defense, those numbers would be much different if you take away three points per game for each team they've played, which they are responsible for adding on.
