In one example, a basketball system includes a basketball goal, a support structure, a connecting structure connecting the basketball goal and the support structure, and a height adjustment mechanism connected to the support structure and the connecting structure. The height adjustment mechanism includes: a biasing mechanism connected at least indirectly to the connecting structure and including a locking pin movable between a first position where the biasing mechanism is locked and a second position where the biasing mechanism is unlocked; and, a handle including an outer surface configured such that rotation of the handle results in a corresponding linear movement of the locking pin as the outer surface slidingly engages the locking pin. The height adjustment mechanism is configured such that a single movement of the handle is sufficient to effect both unlocking of the biasing mechanism and adjustment of a height of the basketball goal.
