The other way to play one pass away, and the one most youth coaches should start with: the gap, or pack line. Off the ball every defender sags a step toward the basket and the ball, one foot in the gap the dribbler wants, so a drive meets two defenders before it meets the rim. This play runs a whole possession against a gap defense: a drive at the top meets the gap defender's stunt, a corner drive meets the post defender's wall, the ball swings across, a middle drive meets a second stunt, and the post entry is surrounded. Why gap instead of deny for most youth teams: the deny concedes the backdoor and the drive; the gap concedes the pass and the long shot, and at this age the pass and the long shot hurt less. Where the advantage lies: the offense can always throw the next pass, but it can never get into the lane, so it ends up shooting over a closeout from where the defense wants. Common youth mistakes: sagging so far that the kick-out is an open three (the closeout is the answer), stunting with the whole body instead of a step, and the gap defender watching his man instead of the ball. Most of what I know about the pack line at this age comes from Teach Hoops' youth pack line introduction and Coach's Clipboard's pack line defense page; read them if you want the whole system.
