#2 Everyone who battles The Fiend goes back to their former gimmick
Kudos to Gary Cassidy from Sportskeeda for coming up with this theory. Everyone who takes on The Fiend reverts to his original persona again. Daniel Bryan went from a man who was confused about whether or not to embrace the 'Yes' movement to one of the most popular babyfaces in the entire WWE roster. Finn Balor became 'The Prince' and went back to NXT, where he is doing a fantastic job.
As for Seth Rollins, he lost to The Fiend and then aligned with The AoP to become RAW's top heel.
It was time for a change for The Miz who did not seem to be at his best as a babyface, in my personal opinion and when he lost to Bray Wyatt, something in him seemed to break and he embraced the heel in him once more, for what should be a very promising run.
