Hold up one t-shirt in a crowded arena. Watch what happens. Twenty thousand people stop. They look. They want it. You point left, they scream. You point right, they match it. You fake left and the whole building groans and laughs. You just took complete control of a room with a piece of cotton that cost four dollars. That's what a great promotions team member can do. And it's one small example of what these teams provide — dance teams, mascots, cheerleading squads, drum lines, ice crews, brand ambassadors — the people who make a sports venue feel alive.
