Guard:
These are potentially your shortest players and they should be really good at dribbling fast, seeing the court, and passing. It is their job to bring the ball down the court and set up offensive plays

Point Guard:
This person is very good at understanding the game, passing and seeing the floor. Like a quarterback in Football this person directs the team

Forward:
Your next tallest players will most likely be your forwards. While a forward may be called upon to play under the hoop, they may also be required to operate in the wings and corner areas.

Center:
Centers are generally your tallest players. They generally are positioned near the basket for scoring and rebounding.
