Every sport has their Tim Tebow or Jeremy Lin, that guy who seems to get about as much love as he does hate. You bring their name up, and it instantly starts a debate between you and your friends.
MMA is one of the sports in the world where you can see your most hated athlete literally get beaten. In other team sports, they make take a few bumps, but odds are, your anti-hero lives to fight another day.
For a fighter, every fight could be their last, so there is always the prospect of seeing your favorite (or least favorite) fighter step inside the cage for the final time. Whether you love them or love to hate them, they always find a way to make you tune in.
