'Once in a Lifetime' they said... Well, by now we should know better than to trust anything supposedly concrete that comes out of the world of professional wrestling. 'Once in a Lifetime' essentially means 'As Many Times In A Lifetime As We Deem Necessary', and The Rock faced off with John Cena for the second straight WrestleMania at 'Mania 29. Rock's matches with Cena most probably exceeded expectations, although in the hyper-cynical word of match evaluation (he says whilst writing a hyper-sensitive ranking of matches) the expectations were pretty low. The second of the two matches was the weaker, if only because of the bitterness that surrounded it. Rocky was WWE Champion coming in, ending the 434-day reign of CM Punk at the Royal Rumble. This didn't please too many fans, a big moment for a still fresh superstar ended to maintain the momentum of a part-time player. The Rock isn't just any part-time player though, and as such there was still a lot to take from this. Still, a focus on past stars over new ones and 50/50 booking leaves this low on the list.
