A basketball system may include a basketball goal and a support structure that is sized and configured to support the basketball goal above a playing surface. The basketball system may also include an adjustment assembly that is sized and configured to allow the height of the basketball goal to be adjusted. The adjustment assembly may include an arm that is connected to the structure connecting the basketball goal and the support structure. The arm may include a plurality of receiving portions, such as openings or slots, and an engaging member may be connected to the support structure. When the engaging portion is connected to a first receiving portion, the basketball goal may be disposed at a first height. Preferably, when the engaging portion is connected to a second receiving portion, the basketball goal may be disposed at a second height. The adjustment assembly may also include a locking mechanism that is sized and configured to lock the arm and basketball goal in a desired position.
