Spend a lot of time on ballhandling . Passing is the name of the game. Ball control is essential and without it, success is impossible to achieve. Along with basic ballhandling skills, at the earliest stage of development, young players must be taught how to draw a foul. Most often, opponents will pass from the free throw, they will find it extremely difficult to move the ball into scoring position.
Most coaches spend way too much time working on offense.
With a young team, use that time to learn to play outstanding individual and team defense. Also, they must learn to defend team defense tactics such as stairstepping, sloughing, foul and dropping, gapping and time switching. Being able to play good defense is essential for the young team. When working on defense, coaching must teach their teams to play counterattack defense. Experienced teams love to take advantage of young teams by pressing and then counterattacking the turnover.
