Closely guarded clarification

[mcdanrd]

NFHS 4-23-1 states that "guarding is the act of legally
placing the body in the path of an offensive opponent."
NFHS 4-10 stipulates that a closely-guarded situation
requires that a player must have control in his/her
front court and be guarded by an opponent who is within
6 feet of the player who is holding or dribbling the
ball. I need clarification on "Legal guarding position"
in this situation. What does it mean to be "in the path?"
