#1 The Undertaker
John Cena's willingness to face the Undertaker could finally bring the legend back from the dead, and while the match has tremendous potential, it would have been much bigger if it had happened a few years back.
The Phenom's in-ring agility has been lacking credibility and his last match with Roman Reigns was legitimate proof of his inability to work a good match.
The Undertaker is the most celebrated performer in WWE history, and since I am analyzing this from a fan's perspective, another match at WrestleMania could unfortunately hamper his legacy.
Since the match will be confirmed next week, a 'Career versus Career' stipulation could add up to the excitement.
John Cena versus the Undertaker will be happening, and if a stipulation gets added, then we could expect the Phenom to finally hang up his boots and end his WWE career as 'the greatest performer of all time'.
