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.
Gabbert's failures in Jacksonville weren't entirely his fault. He has a rocket for an arm, good athleticism and plenty of football smarts, but the No. 10 overall selection in the 2011 draft never had the good supporting casts or coaching that he needed to develop. Gabbert wrapped up his three-year Jacksonville career with a 53.3 completion percentage and a 22:24 touchdown-to-pick ratio. As strange as it sounds, he is the frontrunner for the No. 2 duties with the 49ers. Can San Francisco head coach and quarterback guru Jim Harbaugh help Gabbert salvage his career? We'll see, but there isn't much reason to think Gabbert will develop into a competent backup. If the 49ers enter 2014 with Gabbert as their No. 2 passer, they must have a ton of faith in Colin Kaepernick's durability. If Gabbert is elevated into the starting lineup for whatever reason - assuming he makes the final roster - the fourth-year pro has no fantasy appeal.
