10. John Cena
Yes, yes, I know - John Cena is currently injured. That doesnt totally rule him out of the equation, though. After all, this is John Cena were talking about. Supercena could very well be on the 'Mania card this year, despite being on the shelf at time of writing. Known to be a ridiculously fast healer even the Cena haters cant forget his shocking return from injury at Madison Square Garden to win the 2008 Royal Rumble you just simply cannot rule out a Cena return, even if conventional wisdom suggests he should be convalescing for half the year. The initial plan for Cena at Mania was supposedly to see him go up against The Undertaker, but if Big Match John manages to somehow recover in time for the event, even the opinion-splitting Leader of the Cenation would be a more well-received opponent to go up against Triple H than Roman Reigns. Some wouldnt be happy to see Cena main eventing yet another WrestleMania, but at least his polarising reaction would be better than the largely negative response sure to greet Roman. Plus, Cena has earned himself plenty of brownie points amongst so-called smart fans since WrestleMania due to the excellent matches he put on during his time as US Champion.
