4. AJ Styles
With the word unexpected being thrown around a lot recently for the Undertaker’s WrestleMania opponent, there’s one name that comes to mind and that name is of course AJ Styles. With Styles already proving to be a big deal in the WWE and with the WWE treating Styles like a star just one month into his WWE career it could be a sign of big things to come for The Phenomenal One. Facing the Undertaker at WrestleMania would solidify Styles as a big name to watch out for in the future even in defeat against the Deadman. If Styles is able to become victorious over Chris Jericho at Fastlane we could very well be seeing the Phenom vs The Phenomenal One at this year’s WrestleMania.
