Cox had three tackles and an interception in Sunday's victory over Philadelphia. Cox continues to excel in place of the injured Tramaine Brock (toe). He now has recorded two interceptions through four games for the 49ers and is making a strong case to stay in the starting lineup even when Brock does return. This will be a situation to monitor going forward, but Cox is proving to be a playmaker on defense and is worth a look in IDP leagues.
