#2 The Ultimate Showdown with the Rock
Roman Reigns has already main-evented four WrestleManias, and like it or not, he would be main-eventing another one this April. Brock Lesnar (and technically Seth Rollins). Triple H. The Undertaker. Brock Lesnar (again). WWE needs someone to carry on the legacy, and there is no one better than the Rock.
The Rock has reiterated in the past that he misses the allure of pro-wrestling and desperately wants to be back in the squared circle. Moreover, he is the favourite to win the 2019 Royal Rumble according to renowned betting website Skybet.
So, after Roman Reigns resists Drew McIntyre's challenge earlier in the night and the Great One obliterates 29 other men, the Big Dog would walk down the ramp and have a stare off with the WrestleMania sign.
Four years earlier, they did something similar. Would the crowd react the same?
