The San Francisco 49ers have faced significant challenges this season, highlighted by their recent 24-23 loss to the Arizona Cardinals. Criticism has been directed toward quarterback Brock Purdy for holding onto the ball too long, contributing to high pressure rates on the offensive line and red zone inefficiencies. Despite their offensive talent, turnovers and poor execution in critical moments have led to the team blowing double-digit leads in consecutive games. Head coach Kyle Shanahan has faced scrutiny for his game management and inability to adjust, adding to the team's issues. Injuries to key players like Christian McCaffrey and George Kittle have also impacted the team's performance, although these are not the sole reasons for their struggles.
