Setup. Keeper in goal. Attackers 18 metres out with a ball each. A line of cones across the six-yard line.
How it runs. Attacker dribbles in and must shoot before the cone line. The keeper reads the last touch. If the ball is tight to the attacker's feet, stay up and K block. If the touch is heavy and the ball is loose, go down and smother it. After each go the keeper says out loud which one it was and why.
Make it harder. Attackers may go round the keeper. Then a second attacker follows in for the rebound, so the keeper has to get up and set again.
With 4 keepers. One keeper, three attackers in a queue. Attacker becomes keeper.
