Under what conditions is a player called for "over-and-back"?

A player is called for "over-and-back" when they establish control of the ball in the frontcourt and then return to the backcourt after having crossed the mid-court line. This rule is designed to prevent teams from retreating to the backcourt to evade defensive pressure once they have advanced the ball past the mid-court line.

For the chosen option, once a player has advanced the ball into the frontcourt, any movement back across the mid-court line into the backcourt while maintaining possession results in a violation. This enforced rule encourages teams to keep the game moving forward and adds a strategic element as players must be aware of their positioning in relation to the mid-court line.

Moving onto the other options, the rule does not penalize a player merely for receiving the ball in the backcourt, nor does it penalize for stepping on the mid-court line. Furthermore, a violation is not established simply when the ball is knocked out of bounds, as this situation involves different rules regarding possession and the location of the ball. These distinctions clarify why the correct condition for an over-and-back violation aligns specifically with a player returning to the backcourt after crossing into the frontcourt.
