#2 It would be the perfect way to lead to an AJ Styles heel turn
Due to the lack of convincing victories during AJ Styles's near year reign as WWE Champion, his baby-face character has been damaged.
Lacking the dynamism that his feuds needed from him as his opponents Shinsuke Nakamura and Samoa Joe dominated the entertainment value as they terrorized his life, his title reign has often appeared to be an afterthought.
When asked to choose between Daniel Bryan and Styles, the WWE Universe is likely to choose the beloved Bryan, who is seeking to win his first World Championship in four years.
Styles could well be booed in this feud and the excitement of an impending heel turn to capitalize on this makes this title clash even more enticing.
Styles has shown himself to be an excellent heel, during his time spent as a bad guy in TNA, New Japan and WWE itself.
It would be a hugely satisfying development, should it occur.
