San Francisco 49ers: Quarterback

An unusual front-office arrangement and unpredictable behavior by the owner—those aren't the only reasons quality coaching candidates initially rejected this job. (The 49ers were lucky to get one of the best young coordinators, former Falcons OC Kyle Shanahan, as their new head coach.) There's also the matter of San Francisco not having a quarterback capable of elevating this team. Colin Kaepernick lacks the pocket acumen, field vision and throwing touch to lead an NFL offense. There's a tendency to think that Shanahan's system, with its emphasis on moving pockets and play-action, can save the 29-year-old. But no. Even on the move, his limitations are problematic. Plus, even in Shanahan's scheme, the QB plays on the move on fewer than half the snaps.
