17. The Rock vs. John Cena
The rivalry between Cena and The Rock pretty much stretched throughout three different WrestleMania events. At WrestleMania XXVII Johnson delivered Cena The Rock Bottom, thanks to which The Miz managed to retain the WWE Championship. One year after that Johnson once again dominates Cena, and it could be seen in that famous match that was named “Once in a Lifetime.” At WrestleMania 29 Cena finally managed to get on top and avenge his defeat. Right after that, the feud between Johnson and Cena started dying down, and it became uninteresting. WWE tried so hard to manufacture a WrestleMania moment that they forgot to plan and work on actually creating that match necessary. That right there is the main reason why after WrestleMania 29 opinions about the clash between these two started softening up, and eventually, no one will care anymore.
