Coach (A) points in the direction that the player BLUE is to dribble
BLUE must dribble at least as wide as the cone in that direction before performing a cross over and cutting back towards opposite cone (shaking the defender)
Upon reaching the opposite cone BLUE cuts hard to the basket and must dribble inside the key (inside the low cones)
To shake a defender the player with the ball MUST move far enough with the ball to force the defender to move his feet.
Once defender is moving cut hard in opposite direction to gain an advantage in order to cut into the key.
Rebounding is the least glamorous thing in basketball and one of the most decisive. It is also almost entirely a habit, which means it is entirely coachable.
Good spacing is only the start. The best modern offences teach players to attack the defence's rotations and play in a permanent 4-on-3 - here is how to coach that read.
The ball screen produces almost half of all professional offensive possessions, yet most teams still teach it as a memorised play. The modern approach trains the read - giving players a framework to decide based on what the defence does, not what the coach called.
