I issues with team sports here as well. DS is 5 and just started basketball. He as well said he likes practice better than games. Probably becaus he gets to actually hold the ball without it being taken from him, like someone said. With him it is also about extreme perfectionism and getting frustrated with himself. (He is not the best player for sure) also the need to always do things the best out of everyone. We see this being a very very long struggle, But I am not about to save him from the reality of life, and pull him out of team sports.
