All defenders must learn how to play good 1v1 on-ball defence. In this drill each player has a partner (opponent) that he goes 1v1 against. Each pair has a ball. Use both ends of the court. The player with the ball starts at the top of the key and tries to make a move, or shoot the outside shot and score on the defender. The defender must stop the offence, box out and get the rebound. The offence gets a point for (1) each basket made, (2) for each offensive rebound and (3) if the defender commits a foul. No second shots are allowed. Each pair keeps track of their score. Have post players paired up with post players, and guards paired up with guards. Play for 10 minutes or so. At the end, the losers have a penalty of 5-10 push-ups. Rotation (see arrows in Picture 1). After a pair has finished their duel, they get in line on the other end of the floor, but switch offence and defence for the next possession. This drill is also great for offensive players working on their 1v1 moves... jab step, shot fake, dribble moves, etc.
