I think its the 3-4 stack, not sure, but its definitely a 3-4 formation. Also dont know if its one play in particular or the formation as a whole but my LDE, Dequan Bowers, lines up as if he is a DT putting himself between my DT and the RDE leaving a huge void on the left side (offenses *right) of my D if the ball is snapped before I can fix it. It has happened more than once and I have to scramble to get him into place. Anyone else experience this?
