Just wanted to chime in for a second and give you all a list of some defensive drills you might be interested in trying out in order to improve your game.
- Full-court Zig-Zag Drill (1-on-1)
- 2-on-2 close out/ box out drill (3-on-3)
- Wing denial into 1-on-1
- Defensive slide (slow motion, game speed)
- Shell Drill
- 5-on-4 transition drill
- Team shooting competition (elbow, etc.)
Hope it helps!
