#3 Neville
If there was ever a heel turn that fans didn't see coming, it was the recent turn by Neville. When Neville appeared at the Roadblock: End of the Line pay per view, fans believed he was there to congratulate Rich Swann on retaining the title.
However, they quickly became aware that Neville had done a complete 180-degree turn in both character and personality. It appeared as though he felt that he was being pitied for his achievements and that the support of the fans for him wasn't sincere.
He attacked his former friend, and with each punch, kick and stomp, Neville showed more personality than he ever had in his time in NXT.
Why the turn? It was quite simple; fans were well aware of Neville's incredible high flying skills and aerial assault, but what he always seemed to lack was an edge, and that lacked edge may have held him back. He has certainly proven a number of people wrong.
After capturing the Cruiserweight title, Neville appears headed for a major push and build towards WrestleMania and is certainly the most deserving person for the same.
