4-on-4, touch-the-line drill
The defense is facing the basket while the offense has its back to the basket. The coach calls out the name of one defensive player (X2). That player must touch the baseline while X1, X3 and X4 retreat to defense.
A coach throws the ball to any offensive player, and the offense attempts to execute a fast break. The defense must talk and work together to cover the open man. X2 must recover quickly to pick up the open man. Have your offense run a motion game.
On a basket, the defense takes the ball out of bounds and becomes the offensive team. The offensive team becomes the defense and must play full-court, man-to-man denial defense. Play continues until a basket is scored.
Emphasis with this drill is on talking, helping and reacting.
