Editor's note: The free-agent signing period begins Wednesday at 1 p.m. This is Part Three of a series that examines the 49ers’ biggest offseason needs and their options in free agency. Previously, we focused on wide receivers and linebackers.
The 49ers entered the offseason one year ago feeling good about Jaquiski Tartt and Adrian Colbert as their starting safeties.
This year, nobody’s starting job is secure after both players struggled with injuries and consistency.
The 49ers received some encouraging production from rookie Marcell Harris, who started the final five games at strong safety.
