Legato- To let the stick rebound (bouncy, bouncy)
Stacato- To not let the stick rebound (stoppy stoppy)
F=MA or ; Force= Mass x Acceleration- Understanding this is absolutely key in understanding your technique.
Rules of Legato-
1. You must put enough downward force on the basketball in order for it to come back up to your hand.
2. You must not trap the basketball between the ground and your palm. There must be space.
3. Once the ball starts to come back up, you must let your hand and forearm travel with the ball, and you must be ready to travel at the rate the ball is rebounding.
