#3: Brock Lesnar
In the six years since Brock Lesnar returned to the WWE, not a year has gone by that hasn't featured some sort of rumour about a match between The Rock and Brock Lesnar.
These two men have only met each other in the ring once before when Brock Lesnar defeated The Rock in the main event of SummerSlam 2002.
Corey Graves deleted his Tweet! More details HERE.
In the sixteen years since they last met, The Rock has gone to become one of the biggest movie stars on the planet and Brock Lesnar has gone on to become one of the most accomplished athletes of all time.
Of all the matches on this list, from a financial perspective, this one could easily be the biggest draw, especially given Lesnar's recent return to the UFC. The two men are megastars and a match at Mania would be a guaranteed way to pull in a potentially record-breaking audience.
