Wolves, At the HS and Colege level the DB's will usually backpedal until they can read the QB's drop. A 3 step drop generally means a drag, cross, out or hitch, so the DB will always want to keep the WR in front of him. A five step drop is usually a deap pass and the DB will cross over and go vertical or cross over to 45. Depending on your D scheme's and the DB responsibilities you should be prepared to use both. If you press the WR be prepared for Safety help and the safety will generally use crossover tech.
