The Undertaker
This is the best way that the WWE could book Cena for WrestleMania. A good old buildup from Royal Rumble with many mid games from the Phenom would always be a welcome sign for the fans.
Now it’s the best decision mainly because of two reasons.
One, Undertaker is yet to be booked for WrestleMania and the most favorite name on the list, Brock Lesnar is nowhere to be seen. The dream match against Sting is not likely to materialize leaving the top guy in the company a credible opponent. Break the streak or continue the streak, the match would be interesting to see because finally it could sow the seeds to make Cena a heel.
Secondly, Cena and Orton, unification all feels like been there done that type of feud and keeping Cena in the title picture won’t make sense unless they decide to throw in Daniel Bryan or CM Punk into the mix.
