The San Francisco 49ers are set to showcase their team in the preseason opener against the Titans, highlighting position battles and the new “fever backer” role for defensive versatility. Quarterback Brock Purdy has impressed, although concerns about the offensive line persist. Rookie Kaelon Black is learning from Christian McCaffrey’s efficient practice style, while the team has made roster moves, signing RB Zamir White and waiving Junior Bergen. Deebo Samuel continues to be a dynamic player, contributing as both a receiver and running back.
