On the face-off restart whistle (or anytime there is a restart above the restraining line), the team should be ready to initiate a "play fast" sequence — alternating the finish — forcing the defense to defend and the opposing coaches to coach (a.k.a. — yell "warnings" of the anticipated sequence — further causing hesitation of the defensive players — allowing the offensive team to play even faster).
On the whistle the two middies without the ball (on the wing on the face off) should read there defenseman
If they are not running back on defense and staying with the middies up top then they can stay high up clearing space down low.
If they do run to the hole the two middies should run with them forcing those two middies who just entered the defense organize with their teammates to be the first slide.
