The problem with WWE turning Daniel Bryan heel and joining The Wyatt Family was due to Bryan being so over as a babyface, someone that fans truly & genuinely wanted to cheer for, that they wouldn't accept him. All members of The Shield are over, but nowhere near the level of Daniel Bryan. When you take into account Bryan's image, the type of person he's revealed to be, couple that with a storyline in which he's frequently screwed out of advancement by corporate executives with such condescending egos that it genuinely irks you, it's made for an epic storyline. WWE bungled their way along in the early goings, but eventually got it right. Bryan shouldn't have been turned heel, it was simply a piss poor booking idea. While Bryan turning babyface again a few weeks later and revealing that it was all a ploy to get Bray Wyatt alone, you could tell that it was extremely rushed. Still, the sight of Bryan perched on top of a cage while leading a MASSIVE Yes chant was pretty epic.
In the case of Rollins, it's a different story. As I said, The Shield isn't anywhere near as over as Bryan has been and Bryan's long since established his own personal identity. Rollins hasn't done that aside from being the best in-ring guy of the group. I don't see WWE quickly turning Rollins face once again, I ultimately see him getting a push. In a lot of ways, I don't think Rollins has gotten the amount of credit he's due as a lot of focus in various stories, articles & rumors have been on either Ambrose or Reigns. From an overall perspective, I like Rollins the most. While Reigns might have an overall better "look" about him and while Ambrose is more polished on the mic, Rollins has the best overall game of the three in my view.
The follow up to this could mean the difference between success and failure. Obviously, people want an explanation as to why Rollins turned on the men who've had his back since coming to WWE. That's especially true after being involved in two classic six man tag matches against Evolution, the second of which took place only 24 hours before his turn. What was the offer Triple H made to him? Did he come to Triple H? Was he sick of being the one in The Shield that wasn't talked about as much? Was he tired of being the glue that held them together?
