5. The Rock vs The Undertaker
Alright, this is where we get into some seriously deep fantasy booking. So, Cena goes over The Rock at Mania 28, which means Cena doesn't need his redemption and rematch and all that jazz. While Cena and Punk contest the world title at Mania 29, The Rock turns up on Raw a couple of months before with a mission. When it comes to Wrestlemania, he's done it all: he's faced Austin, he's faced Hogan, he's faced Cena. The one thing he's never done? The last mountain he has left to climb? The Streak. Cue an Attitude Era redux so big it threatens to cause a wormhole in the very fabric of time and space itself. The Rock, the international, multimedia megastar who has transcended the wrestling business further than any other star in history, coming back home to try and break the greatest streak in pro wrestling. It'd be massive, it'd be money, and it would make for an amazing few weeks of television and, we'd like to think, a solid, storied match. Pretty cool, right?
