The game of basketball consists of two styles of play. One style is the half-court offense. This is where teams methodically run plays and set picks to create an open shot against a set defense.
The other style of play is the fast break. A fast break is when an offensive player runs the ball up the court in a hurry trying to beat the defense up the floor and create a lay-up or an un-contested jumper.
