#5 AJ Styles (face)
How good is AJ Styles? Very good is the answer - or phenomenal if you're a fan of puns. Even as a heel Styles has been putting on some of the best matches in the company and it's that kind of talent that led him to become Wrestler of the Year for 2016 in the eyes of many wrestling publications. Pretty soon, the fans are going to just turn him face themselves based on their support.

Following Mania and a likely victory over Shane McMahon, the smartest possible move for WWE would be to turn Styles face and give him the much deserved one on one title rematch that he has earned - against Bray Wyatt. It'd be a fascinating feud between the two talents and even if he doesn't reclaim the gold, it would prove that the guy is still a main event player.
Onto a man who knows AJ quite well.
