Had a great 2018: AJ Styles

In the world of professional wrestling, you can never say never.
Like, for example, you shouldn't say "AJ Styles will never work for WWE."
Also, you should avoid saying "AJ Might work for WWE, but he'll never be champion." Don't forget "AJ Might be champion, but he will never have a memorable run."
As it turns out, AJ had no trouble getting over with the WWE Universe. In a rare move, WWE had him bypass NXT completely and instead make his debut at the Royal Rumble as a surprise entrant. From there he would feud with industry heavyweights like John Cena, and wound up wearing the Smackdown Live world championship for nearly a year.
AJ continues to dazzle and impress in a WWE ring, which is as pleasing as it is surprising to long time wrestling fans.
Will 2019 be just as good to him?: AJ Styles is on the top of the world right now, even though he recently lost his title to Daniel Bryan he is still the number one draw on Smackdown, and possibly all of WWE. With that much momentum, and a dream Wrestlemania 35 match in the works, things look good for Mr. Styles.
