4-2 if they're in tight, but you'll need your outside linemen and linebackers to fill the holes well. The defensive ends have outside contain, but they can't shoot up the field and allow a huge cut-back lane. Linebackers must read pass, and react to the run. I'm not in much of a position to help; cause we've been torched by quick teams. However, the defense works; your defense just has to play their responsibilities.
