#2 Brock Lesnar squashes Balor
WWE really love having Brock Lesnar squash top stars. Remember how between 2015-2018, Lesnar ran through every opponent (minus Goldberg on one occasion), all so that he could put over Roman Reigns?
In fact, WWE even gave Brock Lesnar a 500+ day title reign all so that Roman Reigns could have the big moment. This meant putting the entire main event scene of RAW on hold for over a year.
Reigns did finally get the big moment but we all know what happened afterwards, and that led to a big change in creative plans. Since Seth Rollins seems to be the one being primed for the big Brock Lesnar match at WrestleMania, it's possible that WWE will want to make Lesnar look as strong as possible.
Defeating Strowman would have given him more credibility, but even squashing a top star in Balor would make him look strong. Hopefully, this doesn't happen.
