I am using one of the Excel downloads to check Recruiting Ratings and noticed that on the DBs tap, (and others), it has a CB and a Safety rating. When I go to my formations (I'm playing D3), I see that for my linebackers, they are listed, LB1, LB2, LB3... etc. So i assume that whatever linebacker is in that position in the depth chart will correspond to where they are in the formation. However, for Defensive Backs, it says CB1 and CB1, and then FS, SS. How do I determine where I want my DBs to be playing within the formation?
