We emphasize making a good pass, drawing a defender away from the action, setting a screen are just as important as making the shot. Every player has a job to do at his position. Every player has value. If everyone does his best at his job, the team does well. I sometimes tell the kids a basketball team is like a bicycle.
Some players are the chain, some the pedals, and some the gears.
It takes all the parts working together to make the bike go. You can have 21 gears, but with no chain the bike goes nowhere. A great shooter with no one to pass him the ball doesn't score. Team can be a a tough concept for 9-13 year olds because developmentally they are struggling to show their independence. At least tell a kid he's a good players because he's smart.
