It happens to all of us. A fighter takes the MMA scene by storm, and everyone rushes to predict greatness. Unfortunately in the cutthroat world of MMA, those predictions tend to fall short more often than not.
An example of a prediction falling through is Rick Story. He lost his UFC debut at UFC 99 but won six straight bouts including wins over BJJ whiz Dustin Hazelett, wrestling champion Johny Hendricks and Muay Thai striker Thiago Alves.
Unfortunately for Story, his momentum has stopped dead in its tracks recently—just like the fighters on this list. They all had a number of passengers aboard their hype train but have seen it run off the tracks as of late. 2012 hasn't been kind to a number of "can't-miss" fighters, leaving many to head back to the drawing board for 2013.
