To the line and back
This drill can be performed by whole team (picture shows only two players).
Player 1 sets a ball to player 2.
Player 2 sets it back and runs to the base line to touch it, and than runs back to perform the same move.
While the player 2 is running, pleyer 1 sets the ball over his hear for 2 – 3 times, and when the player 2 goes back the same move continues.
