One could argue that the sport of MMA is the easiest one to see an underdog burst through the ceiling of limitation and find success. At every level of the sport, it takes one mistake standing up or on the ground for anyone to find a victory.
Over the history of the sport, there are countless times that fans have either had their dreams crushed or even sometimes their bank accounts. Imagine you place a nice bet on the recently retired Shogun Rua when he came to the UFC. You see he is matched up with Forrest Griffin and you can’t load enough money into your Match.
