My sportsbook posts total team point estimates for the season. Last year I used these to predict over/unders:

It went 10-4-1 +6.7 units

I did the same for this season, here are the results:
ARZ o8 -110
BAL u8.5 -130
BUF o6.5 -120
CAR u9 -110
CIN u8.5 -125
HOU u8.5 -115
KC u9 -120
MIN u8.5 -125
NO o8 +120
NE u12.5 -120
NYG u9 -110
OAK u9.5 +135
PIT u10.5 +110
SEA u10.5 -105
TEN u9 -135

Good luck
I can post the numbers if someone wants.
