As of right now, Braun Strowman's WrestleMania fate is entirely in the hands of Vince McMahon. While WWE was initially planning on using the Monster Among Men as a replacement for Roman Reigns in the Universal Championship match with Brock Lesnar, it's said the company is no longer concerned about the release of that documentary which could point to The Big Dog being a steroids user.
That's why Strowman now appears to be on a collision course with The Bar at the Showcase of the Immortals but Dave Meltzer points out that WWE originally had a different idea in mind for him.
Apparently, Sheamus and Cesaro would have hit the ring complaining about not having an opponent only to be confronted (and then more than likely destroyed) by Strowman. However, plans changed when it became clear Roman would compete in the main event, hence why the storyline has sped up. It's also noted that it's up to Vince whether or not Strowman gets a partner or goes it alone.
What are you hoping to see from Strowman at WrestleMania? Are you rooting for him to win the tag team titles singlehandedly or do you think he needs a partner? Let us know in the usual place.
