i just graduated, and i never played a sport in high school, but i did work with the band a lot, so i would be the person running around with the props on the field during marchingband season.
i consider that to be
almost the same thing.
in my senior year book the listed me as part of the band, titled "band-aid" lol.
i carried their equipment, and zipped their jackets and helped with costume changes (our senior half-time show had a costumed member.) and i moved props, during the show itself.
