See YouTube video - Spurs offensive concepts
Coach passes to 2 or 3 (either wing, the middle is tough), their defender touches halfcourt before defending, it's a temporary 3-on-2. Rotate offence to defence, next attackers are waiting.
They play so many games in the NBA, their legs are dying, do this instead of 5 on 5.
Brad Stevens - 4 on 4, attackers swing the ball, coach calls the name of one defender who has to touch halfcourt, try to get layups.
