#2 Winning the title
2015 was a hard year for Roman in terms of his booking, with the fans slowly starting to turn on him beginning at the Royal Rumble. By the end of the year, things were still looking rocky, so Vince McMahon of all people decided to insert himself into Reigns’ feud with Sheamus for the WWE Championship to try and help the rise of The Big Dog.
In short, it worked. Big time. The night after TLC Reigns defeated Sheamus for the championship in the same place that he was booed out of the building 11 months prior. This time, however, he was cheered like a full-blown babyface as he lifted the title up high and soaked in the adulation of the thousands in attendance.
A lot of things can happen in a year.
