[dubious elise]

To elaborate on what Amy said, at BMR, we had the balls in small clothes hampers but human players were allowed to move them from place to place. Eg: if there was another human player on the same goal as myself, we would put the balls between us (behind the goal) - the person on the outside would collect balls as they were dumped into the lower goal (they needed to be removed as quickly as possible to prevent scoring errors) and the person on the inside would grab balls from the high goal trash can. Though space was somewhat limited, we didn't have much of a problem unless the coaches were wandering around in that back space. Otherwise, human players had free reign.
