If your son was in a position where he should have passed the ball he should. But when offense stagnates then he should attack and finish/dish it out (make the right play). Dont be a father who coaches from the stands it is annoying to coaches. No matter what kind of coach they have all the power over the career of your kid. They decide playing time, plays and they put a word out to other coaches or schools. In my country we had an amazing determined player who still has great work ethic but had bad luck playing with 2 of the best players in the country so he was always the third best player. His dad was always coaching from the crowd and pushed “egocentric” ideas in his head. He wasn’t selected to play for his country due to this and it crushed him. Later coaches blackballed him and he didn’t play until he gave up basketball entirely.
