Duke

Line up with one player at the free-throw line and three lined up on and between the low blocks; the inbounder stands out of bounds under the basket. This play works best when three different players — 1, 2, and 3 — can all hit an open outside shot, so any early look should be taken if it's there.

The center opens the play by screening for the low corner player, who pops to the corner for the first live catch. A beat later — timing matters here — the best screener sets a down screen for the free-throw-line player, sending him to the top of the key, then immediately turns and sets a second screen for the inbounder himself, who cuts in from the baseline to the wing.

By now the ball has swung from the corner to the top of the key and out to the wing — three different players have each been screened open in sequence.

Once the wing player has the ball, the screener sets one final cross screen — this time for the post player. From there, the post has a real choice: post up on the low block for a quick pass and score, or sprint up and set a screen directly on the wing defender.

That second option is the Ram Screen, and it's what makes Duke dangerous. Because the post's own defender was just used to screen him, that defender is trailing the play and can't help on the screen — leaving the wing player with a clean driving lane and a post defender closing out late.

Every player coming off a screen in this play should be thinking catch-and-shoot first — with this many screens running, someone is reliably open.

The Ram Screen only works because of the defender who gets used up screening the post — teach the post player to sprint into that final screen with real pace, not a jog.
