Strength of schedule is calculated from the opponents projected fantasy points allowed for the QB 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.
Colin Kaepernick's play declined sharply during a disappointing 49ers season that was marred by widespread dysfunction, but Gabbert made just one regular-season appearance for mop-up duty. San Francisco's refusal to sit a struggling Kaepernick tells us that Gabbert's skills haven't improved since his disastrous three-year stint with the Jaguars. Gabbert hit the field for the 49ers in four 2014 preseason contests, connecting on a dismal 46.8 percent of his throws. It would be a surprise if Gabbert didn't face some serious training camp competition. If he is pressed into starting duty for whatever reason - assuming Gabbert makes the final roster - "Plain Blaine" should remain off your fantasy radar.
