See YouTube video - Dribble handoff drill.
2 passes to 1 and sprints out to the 3-point line.
1 catches with split feet, takes a left-hand dribble, changes direction to attack the mid-line, makes a dribble hand-off to 2 (a pitch) and gets out right away.
2 runs through the DHO, puts the ball down and out with his inside (right) hand, kicks the ball back to 1 with a jump pass over the top then exits, 1 shoots.
Variation - 2 shoots behind the DHO, see YouTube video - Partner dribble hand-off actions (both players shoot).
3 goes next with 2.
Continue, switch sides.
