4 Great Basic Basketball Drills for Kids - Pick and Roll, Fakes and Finishes 

The player screening is rolling too early. Need to teach the ball handler not to leave a gap between the screen and themselves. Have the ball handler brush shoulders with the player setting the screen in order to reinforce the "no gap", and have the player setting the screen roll only after the ball handler has brushed past them.

with the pick and roll, you need to have a defender for your drill, especially for youth. The roll is too early and close, you need to give the ball handler space, remember there will be 2 defenders there as well.

I don't recommend the 2nd roll

Turn off the annoying music or at least way down 🥴
