The coach rolls a loose ball onto the floor; whoever wins it attacks and the other team has to recover.
Winning the chaotic first two seconds nobody practises. A rolled ball with both teams chasing teaches players to win possession with two hands, then flip instantly into attack or sprint-back defence.
In games: Games are full of loose balls and neither team is ever ready. Your team learns to arrive first, call possession loudly, and either run the break or protect the rim without a coach's whistle.
U10: roll the ball clearly to one side and coach the break that follows. U14–U16: make possession a genuine contest, and add the corner roll or two-ball version.
1 ball, full court
Two teams of three or four lined up on the half-court line facing opposite baskets. Coach stands on the sideline with the ball.
Games are full of loose balls and neither team is ever ready for them. Practising the chaotic first two seconds — and the instant transition that follows — is worth more than another set play.
Roll the ball clearly to one side so the possession is obvious, and practise the break only.
Roll two balls; the team that wins both scores double.
Roll it toward a corner so the winner has to escape pressure before breaking out.
Throw it off the backboard instead of rolling it, so it starts as a rebound.
