#3 Rowan shakes off his previous allegiances
To some, he will always be Erick Rowan from the Wyatt Family. To others, he will be the dude with the mallet from the Bludgeon Brothers, forever. Maybe the idea is to repackage Rowan into a new character now. One who could serve as muscle for Daniel Bryan.
I personally like this idea, because Bryan joining the Wyatt family makes no sense now. He has a good thing going with his preachy, annoying character and for him to join the Wyatts would be very odd indeed.
It also allows Rowan to play a character that he has never played through his WWE career. A big tough dude not steeped in fantasy and the supernatural.
Maybe Daniel Bryan and Erick Rowan could become a unit that even challenges for the Tag Team titles down the line someday.
