Defense

Defense is the easiest skill to learn for a basketball player, in weeks you can become an expert. However, every defense is got to know how geometry is implied so they can know how they can (1) steal more balls, (2) avoid being tricked and (3) stop their mark from scoring. 

1) Stealing: defensive body position enables you to move quickly in any direction. The feet are slightly greater than shoulder-width apart. The body is low to the ground with the knees bent. The back is straight, not bent. Put your weight on the balls of your feet. The fingers are spread apart ready to catch the ball.

2) Confidence: in defensive position, an instant of improper movement like sliding gives the offense an opening. You need to practice staying with the offensive player. Practice maintaining a distance of from two meters to as little as one foot from the mark.

3) Not losing your mark: always force the offense to one side or the other whether or not they have the ball. You need to be aware of which way, right or left, the offense likes or wants to move, and then prevent them from doing so. Forcing involves setting up at about a 45º angle to the mark, one foot to the side. This positioning makes it easier for the mark to go around you one way (the way you want them to) and more difficult to go the other way.

Once again, it is VERY IMPORTANT to be careful with the defensive angles at which you stand your man, when you are half-sided, you have an advantage, as he cannot get pass you as easy as if you faced him directly with no body angle. The same is applied to the angle of you legs on defensive position, the more folded your legs the faster you are. Finally realize that when you displace with the balls of your feet, you also are faster, as there is faster contact with the floor.
