#4 AJ Styles

AJ Styles has been a featured part in each WrestleMania he has been in since he debuted with WWE. Facing off against Jericho, Nakamura and Randy Orton all at WrestleMania. Styles is someone WWE officials count on to help deliver marquee matches and help with the in-ring style younger fans seem to enjoy.
However, where would Styles fit into this year's show in Tampa? He seemed to be in a feud with Randy Orton and then injured himself getting eliminated by Edge in the Rumble. So could WWE just plug Styles into the white-hot feud and have a triple threat at WrestleMania?
Another option for Styles could be for Styles to face off against an up-and-comer. Maybe have him go against someone like Aleister Black?
Finally, with The Undisputed Era appearing to be dropping all the gold at the upcoming NXT Takeover show and Raw and NXT having talents moving back and forth a bit. Why not have Styles team with Gallows and Anderson to take on the Undisputed Era?
