The 49ers have spent the past four weeks evaluating the roster general manager John Lynch and coach Kyle Shanahan inherited.
Lynch, a nine-time Pro Bowl safety and Hall of Fame finalist, not surprisingly has spent a lot of time looking at the players the 49ers have at the position he played.
In the new Seattle-based defensive scheme under new coordinator Robert Saleh, the 49ers will play a lot of single-high safety. They are looking for someone who can track the ball and make plays in center field.
Lynch said the 49ers will certainly consider moving Jimmie Ward back to the deep middle after he started 10 games last season at right cornerback.
