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.
In a position eerily reminiscent of one or two other teams at this level, the Panthers do possess talent on their roster, it's just not in enough quantities or evenly distributed. The criticism for both their defensive line and secondary play last year was warranted. Fortunately, one of those areas was bolstered with the additions of Star Lotulelei and Kawann Short on DL. If the secondary can gets the same amount of attention paid to it next season, this defense has potential.
