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".
