Sprint back, stop the ball, and match up when outnumbered.
Defending outnumbered without panic. Starting the defence a player down forces the priorities in order — sprint below the ball, stop it, protect the rim, then talk match-ups as help arrives — because there's no time to guard your own man first.
In games: Stops the easiest baskets in youth basketball — the game-day layups that come when your team trots back after a miss and nobody stops the ball.
U12: expect ball-chasing and silent scrambles — celebrate the first talk. U14–U16: handle 4-on-3 and 5-on-4 with loud, organised match-ups every rep.
1 ball, full court
Offence starts with a numbers edge (e.g. 3-on-2) going one way.
Most easy baskets come in transition — practising the scramble back prevents them.
Make it 4-on-3 or 5-on-4.
Award the offence a free basket if both defenders don't call their match-up out loud.
Ban dribbling for the offence so the ball flies up the floor and the defence must truly sprint.
