Dribble drive motion

The dribble drive motion is an offensive strategy in basketball, developed by former Pepperdine head coach Vance Walberg during his time as a California high school coach and at Fresno City College.

The offense was popularized at the major college level by John Calipari while at The University of Memphis, and was sometimes called the "Memphis Attack". Originally called 'AASAA' by Walberg (for "Attack, Attack, Skip, Attack, Attack"), the offense is also sometimes known as the 'Walberg offense' or abbreviated to DDM, and has been described as "Princeton on steroids".

The offense focuses on spreading the offensive players in the half court, so that helping on dribble penetration or skips becomes difficult for the defense, because the help will leave an offensive player open without any defenders near him. As an example a guard can drive through the defensive gaps for a layup or dunk, or pass out to the perimeter if the defense collapses onto him.

Like the Princeton offense, the Dribble Drive offense is a "four-out" offense - that is, only one post player (generally the center) plays near the basket, while the other four players play on the perimeter, around the three-point line. Unlike the Princeton offense, which is based on players cutting towards the basket, and other motion offenses which rely on players screening for each other, the Dribble Drive uses a player (usually, but not limited to, the point guard) to dribble-drive towards the basket. The offense is designed in a way that makes it difficult for the defense to help on dribble-penetration without giving up either a layup or an open three-pointer. Depending on how the defense responds, the driving player can either shoot a lay-up, pass to the post player for a shot, or "kick-out" pass to one of the perimeter players. If the ball is returned to the perimeter, the player that receives the pass either takes a three-point shot, or dribble-drives to the basket, restarting the process.

Like most motion-type offenses the Dribble Drive is predicated on reading the defense rather than set plays, as it relies on the speed and decision making of its players. "I feel we're teaching kids how to play basketball instead of how to run plays" says Walberg of the offense. Coaches that rely upon the offense have said that they do most of their coaching work in practices rather than games. However, the offense contains a lot of initial entry sets, which are used as starting-out points. The sets serve as a way to get the defense different looks, a way to feature a certain player, or exploit a defensive weakness.
