Strength of schedule is calculated from the opponents projected fantasy points allowed for the DEF position. The best rating is +16 which gives the player the advantage against the defense and indicates an easy opponent, the worst rating is -16 which gives the defense the advantage and indicates a tough opponent.
A shaky secondary that barely eclipsed 10 interceptions last season and an injured Clay Matthews left this unit bereft of big play potential. Matthews will be back healthy in 2014 but the secondary doesn't appear any better. The acquisition of defensive end Julius Peppers doesn't seem a fit and he is light years past his prime. Not an every week starting defense from a fantasy standpoint
