Antonio Rogerio Nogueira vs Rameau Sokoudjou Tops List



There have been some massive upsets over the years in the sport of mixed martial arts.

When you combine the number of eyeballs on the fight with the odds for the two fighters going in, the Ronda Rousey vs Holly Holm fight likely provided the most earth-shattering upset in the history of mixed martial arts. You had the seemingly unbeatable Rousey, on the verge of becoming one of the biggest celebrities in the world, taking on the seemingly overmatched Holm. We all know how that fight played out, with Holm landing a vicious leg kick in round 2 to seal the victory.

As has been said many times before - mixed martial arts is such a great sport because you truly never know what is going to happen, and anyone can win on any given occasion.

Of these fights, only two occurred in the UFC, though they involved two of the biggest names that the sport has ever seen - Georges St. Pierre and Ronda Rousey. St. Pierre bounced back from his loss to become more dominant than ever - will Rousey be able to do the same?

One could argue that since the UFC is the highest level of mixed martial arts, there are less severe mismatches which results in less potential upsets. After all, you are likely a very good fighter if you end up making it to the UFC (CM Punk excluded).
