Pass the Rock

Half the group stands inside the paint, each with a ball, while the other half spreads out beyond the three-point line without one. For 30 seconds, the ball-side group tries to complete as many passes among themselves as possible — one point per completed catch — while staying inside the paint the whole time. Swap groups and challenge them to beat the previous score. With so much simultaneous passing in a tight space, players quickly learn to make eye contact with a target before throwing.

This drill comes from MOJO (yougotmojo).
