What to watch.
Watch where the player starts and where the player ends up. A wing can attack a close-out, cut behind a defender or help on a rebound.
Avoid the shortcut.
“Small” is a position label, not a fixed height requirement. Compare the task within the lineup rather than guessing a role from height alone.
These are conventional roles, not five boxes every possession must fit. Use the positions overview to compare responsibilities across a lineup.
