This drill is a regular 5 on 5 scrimmage. The difference is that a second smaller ball is used. In addition each player must have their own basketball, and maintain their dribble constantly during the scrimmage. No player can participate in the action of the scrimmage without their ball and dribble.
The game of 5 on 5 can be played to 3, 5, 7, 9, or 11 baskets.
What makes this drill different from a regular scrimmage is that you can only score with the smaller ball. The bigger ball is dribbled in opposite hand when you shoot. You can advance the small ball with the pass, but an offensive player can only advance the smaller ball if they have control of the dribble with the bigger ball in the hand opposite the small ball. The dribbler can exchange the dribbled ball and smaller ball to go left or right with the dribble or they can advance the smaller ball to a teammate by the pass.
If the player loses either their dribble with the big ball, or possession of the smaller ball they must immediately put the smaller ball on the floor, and it is a free ball for both teams. The same is true is the small ball is dropped during a pass or catch attempt.
Each player on the defending team must also be dribbling a basketball, however they can play aggressively to knock the smaller ball out of the hand of the offensive player or knock their regular basketball away.
This is the primary way for the defensive team to gain posssession, or by stealing the pass of the smaller ball. No large balls are ever passed, only dribbled. Again, you only score with the small ball.
10, each with a regular basketball. 1 small ball is also required.
This is a very good drill to teach players hand-eye coordination while dribbling a basketball. You will see that their concentration will become quickly divided as they try to pass or shoot the smaller ball. This may cause them to lose the bigger ball. This is similar to game conditions where a player needs to be able to read a play and have their eyes independent of the dribble.
You can also play this 5 on 5 scrimmage game, where each person dribbles a smaller ball, and only the bigger regulation size game ball is used to pass or shoot.
