The surprising and controversial announcement that wrestling is being dropped from the core Olympic programme effective with the 2020 Summer Games made me think that we may have found a reason why it matters whether something is a sport or not: Whether something is a sport (as opposed to a game or a competition) should be a tiebreaking factor when choosing between two events. In other words, when the IOC is deciding between wrestling and, say, synchronized ballroom dancing, the former wins out because it is a sport and the other is not.
