No. 5: Inside Linebacker Jonathan Bostic

2016 Cap Hit: $942,381

San Francisco’s inside linebacker corps’ depth was tested to the extreme this season, with linebackers NaVorro Bowman, Ray-Ray Armstrong and Nick Bellore all suffering season-ending injuries at various points in the season.

It’s highly unlikely fellow linebacker Michael Wilhoite returns to the 49ers next season, but adding some depth via NFL free agency would be a wise move.

Current Detroit Lions linebacker Jonathan Bostic missed all of 2016 with a foot injury, and that should drive down his price substantially.

While never tabbed as a regular starter, the former second-round pick of the 2013 NFL Draft does have the capability to double on special teams, which offers San Francisco some much-needed help within that unit as well.
