One thing that is interesting to note is that **if** the safeties operate as described by Norbert and Oriolefan, why in the formation setup is the FS closer to the line and the strong safety deep in the 4-3 and 3-4, yet the more common setup with the FS deep and the SS shallow is utilized in the nickel and dime ? In other words, if you want a rangy safety in the prototypical FS mold to cover the deeper zone and a hybrid type in the SS to cover the shorter zone, you can't set that up to work every time without drawing from customized depth charts to override the regular settings. I think the regular settings will switch your safeties back and forth in terms of depths depending on which formation is used. CS never responded to an inquiry about this. Been waiting since 2015 for an answer after receiving a "we will respond to this shortly" initial response.
