#1 The Rock

We were actually going to go with John Cena here, but the more we thought about it, the more this made sense.
While Dwayne Johnson's returns to the ring have been, obviously, more frequent than Shawn's, any time The Rock returns to the ring is an event. And not just because he's one of the biggest movie stars in Hollywood (though that helps). He's a sure-fire Hall of Fame member - and the fact that he's not already in, makes us think that he's not ready to hang up the boots.
Also, consider the fact that Mr. WrestleMania and The Great One have never (and THE ROCK MEANS NEVER) faced off in the ring before. They were supposed to, but it never happened. That program was supposed to take place in the early 2000s, but because of some apparent personal issues between the two, it never happened.
That was years ago, plenty of time to heal old wounds. Plus, with all the extra money WWE has to work with these days, they might be able to make both of these legends a deal they can't pass up.
