Posted this another thread, but thought the trend was interesting enough for a new point.
Looking at historical SB lines, Vegas screws up on the favorite every other year.
- Even years, the favorite scored 15.1 points below the Vegas team total expectations.
- Odd years, the favorite scored 3.7 points above the Vegas team total expectations.
- Other than SB 47 and 48, Vegas has been nearly on point on the underdog line (0.7 points above Vegas line for TT).
- In the even years, Under is 4-1
- In the odd years, Over is 4-1 (and the one loss was 1 point away from hitting over)
Conclusion (if you believe the trend carries any weight):
- NE 34 vs ATL 28
- Take Over 58
- Take NE -3
