The lack of depth drops back into the safeties with Jaquiski Tartt out again Sunday with a rib injury. Harris will take over the starting job for the second week in a row. Harris played well against Baltimore, but really struggled against the Saints and missed multiple tackles. The Falcons aren’t afraid to take deep shots while also throwing underneath to Austin Hooper. Harris will need to be on top of his game in order to prevent big plays, especially to the tight end.
