Can an introverted young basketball player improve his game if he gets nervous playing in front of others

A basketball player will improve his game under any environment as long as he is playing basketball. You can be 6 years old playing on the playground or a 10 year veteran in the NBA who has won 7 championships, but the more you play basketball, the more you improve your game.

The introverted kid will learn how to play in front of others and will become better at playing in front of crowds. Eventually, his nerves will disappear or lessen.
