#4 Sami Zayn vs Braun Strowman
Maybe there isn't much to it and the storyline between Sami Zayn and Braun Strowman continues till WrestleMania. While Zayn winning the title may be satisfying for so many fans, the conclusion to that match was not so satisfying for the babyface.
Strowman could get a one-on-one rematch against Zayn for the Intercontinental Championship at WrestleMania, with no outside interference allowed. Maybe, Shinsuke Nakamura and Cesaro disassociate themselves from him in the build-up, leaving him all alone to get squashed by the Monster Among Men at the Show of Shows.
If he will remain the obnoxious and annoying mouthpiece, then this is a very big possibility. It would give Braun Strowman a singles title victory at WrestleMania, while Sami Zayn receives his comeuppance in the grandest way possible.
This may be where WWE is going with him and Strowman as we are approaching 'Mania. Zayn could use the post-WrestleMania period to re-evaluate his career and possibly come back stronger, as a babyface again. One can hope.
