5 Surprises that can happen on SmackDown: WrestleMania 37 main eventer to return for title match, big backstage conflict revealed?

#2. The Fatal-4-Way match happens on SmackDown and not WrestleMania Backlash

Apollo Crews and Big E

Apollo Crews lost to Big E by DQ last week on SmackDown, which meant that the Intercontinental Championship didn't change hands. Kevin Owens found himself involved in the post-match beatdown as he saved Big E. His rival Sami Zayn followed suit, and a Fatal-4-Way seems to be in the works.

It would be a big surprise if WWE booked an Intercontinental Championship match for SmackDown rather than the PPV. It would result in good ratings, however.

#1. Seth Rollins defeats Cesaro

Cesaro and Seth Rollins

The big WrestleMania 37 rematch will feature Cesaro taking on Seth Rollins. Since Cesaro is being built as Roman Reigns' next Universal Championship challenger, it's hard to see Seth Rollins winning this one.

But WWE has kept Seth Rollins strong in the last few weeks, and a big surprise would be if he beats Cesaro. It wouldn't be a clean victory, but one that could either cause another roadblock for Cesaro - or a big mix-up in the Universal Title picture.
