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

'A special episode of SmackDown is planned for this week, with an "old school" and throwback theme advertised. We're not sure what WWE plans to do to give the episode an old-school feel, minus a change in set and presentation, but we have a few ideas.

There is a WrestleMania 37 rematch advertised, and that should be one of the focal points of SmackDown. It's hard to argue that SmackDown hasn't been better than RAW lately, and this episode could result in a one-sided interest for WrestleMania Backlash.

While SmackDown has done well to build their side of the WrestleMania Backlash card, RAW hasn't. Here are some big surprises that could happen on the Throwback episode of the Blue brand:

#5. Sasha Banks returns to the SmackDown Women's Championship picture

Sasha Banks has been absent from WWE TV since WrestleMania 37 - where she lost the SmackDown Women's Championship to Bianca Belair in the main event. Post-WrestleMania, Bianca Belair's first title feud has been against Bayley - the longest-reigning SmackDown Women's Champion in history.

It's the right direction to go in, especially for Bayley, who missed out on a match at WrestleMania 37. SmackDown has been the better brand, and there haven't been more than six women featured at a time - four of whom are involved in the Tag Team Title picture.

A big surprise would be the return of Sasha Banks. She is recently coming off the best title reign she's had in WWE, and the blue Brand has missed her for the past few weeks.

With that said, it isn't a great idea to add Sasha Banks to the SmackDown Women's Championship match at WrestleMania Backlash. The WWE Championship match and the RAW Women's Championship match have had participants added, making both of them Triple Threat matches as a result.

With another multi-person title feud already teased for WrestleMania Backlash, it isn't a necessary addition.

#4. The power struggle spills over to SmackDown

A power struggle has been brewing on RAW

Both RAW and SmackDown are managed by Adam Pearce and Sonya Deville (on-screen, anyway). While Sonya Deville is supposed to be lower on the pecking order, she has taken certain matters to her own hands, much to the frustration of Adam Pearce.

We're referring to the power struggle that the two authority figures have had recently, especially after Sonya Deville reinstated Charlotte Flair without Adam Pearce's consent.

The backstage conflict could continue to brew on SmackDown, which would be a bit surprising - but it makes sense. It's good to see storylines that can spill over from brand to brand.

#3. Aleister Black makes an impactful return to SmackDown

Aleister Black's return to SmackDown is imminent. We haven't seen him on WWE TV for over half a year now. Since he wasn't part of the April 15th WWE releases, the question became when and not if Aleister Black would return to SmackDown.

What we know for sure is that he is returning as a heel. But what if there is a twist and he returns as a babyface?

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

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

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.
