Fans love watching an underdog cause an upset. The problem is that unbeaten teams are unbeaten for a reason
A classic narrative, dating back to the classic matchup of David v Goliath, is the underdog v the favorite.
The only problem is that the underdog is an underdog for the reason. Sure, everyone loves it when a David wins, but Goliath usually swats him away with predictable ease and then pounds him into the dirt. Which leads to a problem: who, other than devoted fans of the team in question, roots for the perennial champions? Isn’t that a bit like watching Hoosiers and rooting for the big kids to beat Gene Hackman’s scrappy underdogs? Or watching Rocky IV and rooting for Drago?
