I know from experience at camps and as a basketball player, that defense wins basketball games. Coach Clem Haskins is also a believer in playing good, solid defense. That is why one area he stresses at his basketball camps is pressure defense. The problem is how do you teach campers from all different levels and backgrounds. One way is to hire people that have basketball backgrounds as coaches.
All campers then start from the same place and learn pressure defense skills the same way.
Care must be taken to explain which number goes with which position, where that player should be on the court, and what their responsibilities are. That is why I have built that component into the set of instructions. Even if campers believe they already have this information, repetition is a good reminder. Practice makes perfect. That is why after the first day of instruction, the remainder of the time is spent practicing drills that allow the campers to play both offense and defense so they can implement what they have learned.
