In “switch” the two defenders swap responsibility for guarding the offensive players. This is most commonly used where the two offensive players are similar (e.g. a “guard to guard” screen or a “big to big” screen), although particularly late in the shot clock a team may switch all screens. In switching, the defender initially guarding the screener must move aggressively to deny the cutter the ball. The other defender must similarly move quickly to establish a position to defend the screener.
