1. The Rock
When it comes to blockbuster, WWE would be giving fans something even bigger than Cena if they did The Rock versus The Undertaker at WrestleMania 32. Now that would be money! Is it a possibility? Yes. The Rock has said he will be at Mania, and WWE have already began hyping it up. It isn't confirmed if he will or won't be wrestling, but there has to be a chance. If it is the case that he's wrestling, McMahon simply has to move him into The Undertaker spot. It would be a massive match, a true global celebrity against WWE's most revered wrestler. That's got to be worth even more money than the Cena bout. Given that magnitude, it is also a fitting occasion for Taker to retire on. He could defeat The Rock in the main event of the biggest WWE show ever. How cool would that be? It is an even bigger and better farewell than the Cena match.
