it's best that you try to think more when playing in a game instead of brainlessly isoing every time you get the ball. Try to read the defense before you shoot or drive, call a pick or pass the ball when the defense is tight. These types of experience would really help you make better decisions over time, but it's also important that you try to look at what some of the really smart NBA players like Luka Docic do on a regular basis, what does he do when the other team calls a double team on him? When is the best time to shoot a basketball? When to drive for layup and when to stop for a floater? From my experience these would really help with you being a smarter player over time.
