Recently a good player told me his game blew up after a summer of hard work.
The best way to play is instinctively.
Get together at a park or court somewhere & play some ball.
Try to get enough players to have some real action.
Play, play and play some more. No referees, no coaches
No calling whiny fouls on all the little contacts.
Try to play as a team. Pass & move. Set screens.
Don't try to run plays. Move instinctively.
Be more aggressive than you might usually be.
Play on an outside court, preferably one that is not smooth as glass
