#2 Roman Reigns/Braun Strowman Double Turn:
Roman Reigns and Braun Strowman had one of the most intense rivalries of the PG era during 2017. All of their matches were highly entertaining and brutal. Their feud peaked with an Ambulance match at The Great Balls of Fire where Strowman was victorious. After the match, however, Reigns didn’t take his loss as a true sportsman and ended up attacking Braun Strowman brutally and even went as far as putting him in an ambulance and crashing that ambulance into a production truck. Fans thought that this was done to turn Roman heel and Strowman face. This angle would have worked for that story-line. Braun was getting very popular with the WWE Universe at that time while Reigns was receiving boos on a weekly basis.
But the following night on Raw, Reigns came out, still as a babyface, bragging about injuring Strowman while Strowman returned as a heel on the next episode of Raw. Braun ended up turning face in October when he was betrayed by his team during their match against The Shield at TLC while Reigns still shows up every week as the top face of the company. The ambulance crashing angle was a perfect way to turn Reigns heel and Strowman a face but maybe WWE has bigger or no plans of turning Reigns a heel.
