Underdogs are easy to root for in any sport.
So when it comes to fighting, fans sometimes gravitate toward an unexpected challenger for the title, otherwise known as a dark horse.
For instance, Frankie Edgar is the perfect definition of a dark horse, or at least he used to be. His popularity skyrocketed when he upset BJ Penn twice and rallied twice against Gray Maynard.
Edgar was a 5-to-1 underdog against Penn and became the champion. So who will be the UFC’s next dark horse? These are the best candidates in each weight class.
