Manningham out: Assessing 49ers' targets

The San Francisco 49ers ran out of depth at wide receiver in the playoffs last season.

They responded by signing Mario Manningham in free agency and using a first-round draft choice for A.J. Jenkins.

Depth is becoming a concern again despite those measures.

The season-ending knee injury Manningham suffered against Seattle on Sunday night will cost the 49ers their most targeted wide receiver other than Michael Crabtree.

The chart ranks 49ers players by most pass targets. Shading identifies injured players. Tight end Vernon Davis suffered a concussion against the Seahawks. His availability in the short term remains unclear. Wide receiver Kyle Williams is on injured reserve.

Jenkins will presumably get meaningful chances. He's had nearly a full season of practice without factoring into the offense yet.
