Detroit is easily best UNDER team in NFL by -9.6 points per game going under 9-2. Chicago off consecutive wins, so Cutler generally comes out flat when his team is playing well.

The Lions offensive and defensive stats explain why they are an under team. Detroit gets .9 fewer yards per rushing attempt and .3 fewer yards per pass than foes normally allow. On the other hand they hold teams to 1.0 yards per rushing attempt and .2 yards per pass attempt below normal average.

Detroit has their best OL Riley Reiff questionable to doubtful. The strength of Chicago is their defense and the stats are distorted because they have been a Peter Principle defense. Bears horrible to elite offenses Patriots and Green Bay twice
48 points per game in three games to great offenses. However, they have been great to non-elite offenses allowing less than 20 points per game in remaining eight.

Strength of both teams is defense and the total is crazy.
