There’s something special about rooting for an underdog. It could be the David and Goliath aspect. It could be the opportunity to be a part of something small that becomes something big. Maybe it is feeding the human urge to know what it feels like to win the lottery.
Whatever it is, the most readily available platform to be a part of an underdog story is sports. Every sport, at every level, has what seems like an infinite number of opportunities to witness upsets. There are David and Goliath stories happening every day in the sports world and this may very well be what makes spectating so entertaining.
