3. Roman Reigns With The Rock vs. Brock Lesnar With Paul Heyman
If Brock Lesnar wins the Royal Rumble and the stage is set for Roman and Brock part 2, the promos with Paul Heyman leading up to the show would be very interesting, but if Rock was to show up to be in Romans corner for the big show, the verbal sparring between The Great One and the former owner of ECW would be classic. On the night in Dallas, the action could be left to Roman and Brock. We know from WrestleMania 31 that those two are more than capable of putting on an excellent match but with Heyman and Rock on the outside, it gives that extra layer of star power, unpredictability and of course the eventual moment where Rock would knock Heyman out with a Rock Bottom.
