After obtaining a legal guarding position, may the guard move to maintain that position?

The correct answer indicates that after obtaining a legal guarding position, the guard is allowed to move in order to maintain that position. This is consistent with NFHS rules, which state that a player in a legal guarding position can reposition themselves as needed to effectively guard an opponent.

Even though a guard must have established a legal position, they are not required to remain completely stationary. Instead, they can move laterally or in any direction necessary, as long as they do not commit a foul by initiating illegal contact with the offensive player or failing to give them space to move. This ability to adjust and remain effective as a defender is essential to proper defensive play and allows for dynamic interaction on the court.

Other options suggest limitations that do not align with the rules. The notion that the guard must remain stationary contradicts the fluid nature of basketball, where players must adapt to constantly changing situations. Restrictions based on the movement of the opponent or the guard's proximity to the basket are not relevant either; good defense often requires movement regardless of these factors. Thus, the principle that a legal guard can move to maintain their position reflects the active role of defenders in gameplay.
