High Drop coverage positions the screener's defender higher up the court to limit space for the ball handler while still protecting the rim and encouraging inefficient mid-range shots.

A slip screen is a quick action where the screener moves as if to set a screen but doesn’t make contact with the defender, instead immediately rolling before the defense has time to establish position. This rapid movement capitalizes on the defenders’ hesitation, even for a split second.

Because the slip occurs so quickly, it often causes the defenders to be late on the switch, leaving the roll man open. Alternatively, if there’s miscommunication and both defenders commit to the roll man, the ball handler is left unguarded for an open shot.

The Ghost Screen operates on a principle similar to the Slip Screen but takes it even further. In a Ghost Screen, the player doesn’t even fully move into a screening position. Instead, the ghost screener fakes as though they might set a screen but quickly cuts past the on-ball defender and relocates to the wing or another open area.

This subtle deception creates confusion for the defense. The ghost screener’s defender often anticipates a screen and calls for a switch, but the on-ball defender, seeing no actual screen setup or contact, is left uncertain about whether to switch. This breakdown in communication frequently leaves one of the offensive players unguarded, leading to an open shot.

While not exactly the same, you can think of the Slip Screen as a "fake Pick-and-Roll" action and the Ghost Screen as a "fake Pick-and-Pop" action.
