#1 Worst: The Roman Reigns push
Roman Reigns has all of the attributes of a big star - be it the look or the legacy. He hails from the Anoa'i family, which has produced some of the greatest in sports entertainment history and was positioned to take over from John Cena as the face of the company.
To be honest, Roman Reigns tried his best, and even put on great matches, but the audience could see his push coming from a million miles away and began to reject him as their chosen one. Vince McMahon was obviously high on Roman Reigns as 'his guy', but the promos that were scripted for him rarely did him any favors.
The fact of the matter is that he was thrust into a position that he was not ready for, and even though Reigns put on quality matches, night after night, the crowd would just not accept him as their guy. It took the knowledge that Reigns was a real-life Superhero battling cancer every week, for the audience to warm up to him and cheer him on.
The heat was so strong that even The Rock coming to Reigns' aid did not get him cheered, and in fact, got The Rock booed!
