This is sure to cause the QB to mess his pants and immediately quick-kick:

All 11 defenders line up in a straight line from outside receiver to outside receiver like 11 linebackers...about 2 yards off the ball. The outside defenders over the receivers will cover man. Depending on the down/yards to go/and formation, certain players are assigned to drop back into coverage and others to rush. It will vary from down to down so the line doesn't know what their blocking assignments would be. Confusion ensues. If they try to run...the RB runs into their own linemen standing there not knowing what to do. Or, they either try to pass and throws an INT because of the defenders dropping back or the QB quick kicks (it's his only real option).
