I'm actually Scott Satterfield just want to make sure this board is legit.
For real tho my original take was that the read for the QB with out knowing coverage would be YZFX going high to low on the strong side and then back to weak side. As soon as the QB see's cover 2 that would theoretically take Y & Z out of the play as Y will be covered by the safety shading to the numbers deep and Z taken out by Corner in the flat. His read then would then first be F deep in the seam between the safeties, if that's not there then hope X is clear of the linebackers on the drag. 3rd option is QB scramble, 4th option is throw it away to the sideline.
