3. The Rock
The Rock and the Undertaker are two of the biggest names ever in the WWE, so it comes as no surprise that these two meeting for the Streak is often talked about as one of the big fantasy match ups. The Rock has beat Stone Cold, Hulk Hogan and John Cena at Wrestlemania. The Undertaker has beaten Shawn Michaels (twice), Triple H (three times) and Ric Flair on the way to his unblemished record. But will it happen? Well, if the Rock does decide to wrestle at the 30th anniversary (and my gut is leaning towards the affirmative) then there aren't that many big stars for him to tangle with. Cena? Check. CM Punk? Check. And it would need to be a star big enough to main event with the Rock - so rising stars are not going to get much of a look in. Having said that, would these two personalities really work well together? The Rock is known for trying to get laughs out of the crowd and using his electrifying catch phrases. A feud with the Dead Man would require a more intense side of the Rock - after all, it's no coincidence that all the faces that the Undertaker has faced over the years have not been clean cut faces, but more grizzled, morally ambiguous ones. But should the Great One come back for a match at Wrestlemania 30, there's no doubt that the Undertaker would be an opponent that will be thrown around as a big possibility.
