5. Conor McGregor- This one may seem obvious, hence the number five position. Connor has talked so much and made so many bold predictions anything less than a first round Knock out of Dustin Poirier will be a let down. Veteran trash talker Chael Sonnen at least had an established UFC career before he created his bad guy persona. The other difference between the two is that Chael did not have an entire country’s hopes riding on his shoulders. Bad guys create hype because people want to seem them lose. Once they do lose, the mystique is gone. If Conor doesn’t win and win big he will watch his potential to be a PPV king evaporate.
