Depending on where you play, you can play whatever you want in your spare time, which varies from person to person.
You are good at dribbling, breaking, passing and playing point guard;
Good at defending and rebounding, serving as center and power forward;
If you are good at shooting, layup and breakthrough, you can play shooting guard or small forward. .
If you are formal, competitive or want to develop your career, 180 plus you are thin, you can play as a defender and at most as a small forward.
Personally, I suggest playing guard. If you are thin, you have good flexibility. 180 height still has some advantages in China. . . You can practice ball control and passing and become an all-around speed point guard. Or practice scoring ability and become a flexible breakthrough shooting guard.
