"Kaepernick is statistically superior to at least half of the backup quarterbacks in the NFL."

He has demonstrated that he is not a pocket passer, russell Wilson while mobile is a basically a pocket passer, albeit they run a scheme that moves the pocket more then most, the fact that the Seahawks In need of a back-up (at that time) with a coach who is very much a SJW type passed on Kap reinforces it's his skills not his protests. Last I looked B Marshall was still gainfully employed (as he should be given his skills).
