Two players: offence one pass away from the ball, defender in full denial (arm in passing lane, palm out, eyes on both ball and man). Coach attempts five passes; defender must intercept or deflect at least three.
This is where great team defence starts: making the easy pass impossible.
Forearm in the passing lane, NOT against the offensive player (that's a foul).
Palm out, fingers wide — bigger target for deflections.
Open stance — see ball AND man on the same plane.
Move with the offensive player — never lose contact.
Get your hand to the ball, not the man.
Three-way drill: coach, offensive player, defender — offensive player can flash to the ball. Add 'back-cut' option — if defender overplays too much, offence cuts behind for a layup. Live with the third defender helping.
