A tweener in basketball is a term, sometimes used derisively, for a player who is able to play two positions, but is not ideally suited to play either position exclusively, so he/she is said to be in between. This term is most commonly used only at the highest level of basketball competition, where players must combine extreme physical talent with specialised basketball abilities. A tweener has a set of skills that doesn't match the traditional position of his physical stature.
