3. John Cena
Although John Cena is currently out with a shoulder injury which has reportedly taken him out of any WrestleMania plans, it wouldn’t be the first time that Cena has miraculously returned from injury a lot sooner than expected. With The Undertaker versus John Cena being one of the biggest WrestleMania matches of all time to never happen, and this year’s WrestleMania being built as the biggest of all time, there’s no doubt the WWE would want this match to take place in front of 100,000 people in Texas.
With the added incentive that John Cena rarely takes a loss at WrestleMania and with WrestleMania being The Undertaker’s yard, it creates an unpredictability on who would walk out victorious. An unpredictability unseen in a match since Brock Lesnar faced The Undertaker at WrestleMania 30.
