Great resource with drills, coaching point emphasis & practice routines broken down by grade level.
Drill is designed to work on types of pivots (inside/outside), being strong with ball and creating space while doing so.
The drill attached combines working on passing, sprinting to closeout and then leads to some live 3 vs 3 play. It is a nice change to the traditional shell and adds a long closeout for your defender. Offensively you can work on driving the long closeout and whatever action you prefer after you pass (basket cut or screen away). Easy to keep score or create your own scoring system.
