She gets frustrated, hangs her head, and then takes plays off. It is not being lazy. She has the highest motor out there. It's emotional.
You see this sometimes with kids who are huge talents and used to having everything go their way. She will mature out of it because I know Kim won't put up with it. Cooper just needs to watch Zakai on the men's team. When he makes a mistake or something goes wrong he doubles down on the other end to make up for it. It is all about habits because I am sure he is feeling some of the same emotions.
