S Anthony Harris (Vikings)
There weren’t many safeties better than Harris in the NFL last season. He’s developed nicely into a ball-hawking free safety and led the NFL with six interceptions this season after posting just three through his first four years. Harris is also an aggressive tackler that would slide seamlessly into the free safety spot of defensive coordinator Robert Saleh’s defense. San Francisco probably won’t afford a player like Harris if they do have to replace Ward, but Harris is one of the only available safeties who can effectively do all the things Ward does for the 49ers’ defense.
