By that I mean you use a 4-3 formation but you are really playing a 3-4.
You make the NT like a 3-4 NT. Then you either
A. Make the weak side DT like a 3-4 DE and shift him outside all the time and make the RDE like a 3-4 ROLB, and then the ROLB like a RILB and keep him inside.
or you make the weak side DT like an ILB (lightest weight possible, so Levon Kirkland) and drop him off the LOS every play.
