The San Francisco 49ers have experienced a significant shakeup in their secondary this offseason, losing key players such as Talanoa Hufanga to the Denver Broncos and Charvarius Ward to the Indianapolis Colts through free agency. This development raises questions about the team's defensive strategy going forward, particularly with strong safety Malik Mustapha still recovering from a serious knee injury sustained last season.

In light of these changes, Ji'Ayir Brown is set to take over as the starting free safety, following a promising second season where he saw substantial playing time. The absence of experienced players may lead defensive coordinator Robert Saleh to rely on less proven talents like Marques Sigle, a fifth-round draft pick out of Kansas State. As the team prepares for the upcoming season, the effectiveness of these new defensive backs could prove crucial for maintaining the 49ers' competitiveness.
