5 WrestleMania main events that shouldn't have happened

#2 The Rock vs John Cena - WrestleMania 29

Twice in a Lifetime

Every single week, for an entire year from 2011 - 2012, on every single episode of RAW and Smackdown, WWE promoted The Rock vs John Cena at WrestleMania 28 as being 'Once In A Lifetime'.

That is one of two reasons why their match at WrestleMania 29 makes this list. Overall the match itself wasn't that bad, it was nowhere near as entertaining as their first clash at WrestleMania 28, but it was passable overall. Simply put it is the mere fact that their first match was promoted for so long as 'Once in A Lifetime' that it makes this list. The Rock vs John Cena II happened for two reasons. Firstly, WrestleMania 28 had been the most successful WWE event ever up to that point and Vince McMahon attributed this to The Rock vs John Cena, and he was probably right for the most part. However, it was the fact that the match was to only ever happen once as to why it was so successful. Vince also felt that he owed John a win over The Rock for allowing Rock to take the win in the first match between them. The second reason why this match is here is that of how predictable it was that John would win, as we all knew he was owed that win.

Former WWE star CM Punk voiced his frustrations over the match, saying it would have been better if he was added into the mix as a triple threat, and he is probably right.
