#3 Would probably ensure that Brock Lesnar will face a different Superstar at WrestleMania 36
We know that WWE doesn’t book rematches for WrestleMania very often. In some rare cases, however, the company is left with no choice but to repeat a match that has happened before at the Shows of Shows. But these cases are different from others. WWE book rematches at ‘Mania only if they have some story to show to the world. Otherwise, they would plan something else for this event.
If Cain Velasquez faces Brock Lesnar at Royal Rumble and assuming he loses again, he would probably not face Lesnar again at least for the next few months. This ensures that The Beast will likely face a Superstar he hasn’t faced before or it’s been a long time since their match.
As per Tom Colohue, the current plan seems to be.
“I think based on current storylines and what certain people are doing, I think it’s more likely to be someone like Randy Orton. I think that’s a match that has a story, has a background. In 2016, obviously Brock Lesnar literally caved Orton’s skull in the middle of a match [SummerSlam], so that’s something they could revisit.”
Randy Orton vs Brock Lesnar is a story that started very well but didn’t end properly, at least for Orton. If WWE books this match for WrestleMania, it would prove to be quite a match.
