I am not surprised. When the entire team is playing well, otherwise-decent players look good. I like Cutler, and I think he gets way to much shit by the fans and media, but the average team is scoring more than 21 points per game.

This site lists 19 teams who scored 22 or better per game (I am not counting atlanta and TB, who scored a fraction of a point better than 21)

Similarly,

this site shows that the average points per game for the entire league was sitting at 22.8.

Again this isnt to shit on Cutler, and I hope that he brings his game to a new level this year. But we shouldnt boast about Cutler's record when the defense holds other teams to below-average statistics.
