Yesterday I shared Part 1 of Ballscreen Shooting which incorporated three different types of screening actions.
The technique the throw-behind in Frame 1, is essentially a quick evade dribble. You are trying to throw the ball out in front of you, in an effort to create separation from the hedging defender, while also making it difficult for the initial defender to recover in time before the quick release jumper.
Do not allow your players to just go through the motions, set a goal to reach during each set. Example: You MUST go 7-for-10 before moving to the next sequence.
