Gmen -3.5

Giants have a injured secondary (is there ever a season where the secondary isnt banged up?) and that is never good.
But having a injured offensive line is even worse. Giants front 4 will be in the backfield all game long.

Defending Super Bowl champs week 1 are 12-0 SU and 9-2-1 (82%) ATS

The last champion to out right lose its Week 1 opener the following season was Denver, which occurred in 1999 and that was because Elway retired after the super bowl win.
