5 Surprises for SmackDown: Big twist in Roman Reigns-Usos storyline, Possible Title change in WrestleMania rematch?

Welcome to this week's edition of potential surprises for SmackDown. This is the go-home episode of SmackDown before WrestleMania Backlash, and the blue brand has undoubtedly had a better build to the pay-per-view than RAW.

The main focus will be the Universal Championship storyline, but there's a lot more at stake as well. Here are some of the big twists that can happen on SmackDown before WrestleMania Backlash:

#5. The Usos and Roman Reigns storyline takes a big twist on SmackDown

Roman Reigns and Jimmy Uso

Last week on the Throwback episode of SmackDown, we saw the formal return of Jimmy Uso after over a year away with an injury. While he made a couple of appearances in between, those were one-offs that were only meant to add to the Roman Reigns-Jey Uso storyline.

Things are different now, however. Jimmy Uso told Roman Reigns that he wasn't going to just fall in line the way his brother did. Refusing to acknowledge him, it led to a tense main event segment where Roman Reigns called out Jimmy Uso to get him onboard.

We didn't get a clear-cut answer, and Cesaro stole the headlines last week by getting a measure of revenge against Roman Reigns and Jey Uso on SmackDown. It will be interesting to see how that dynamic plays into the storyline with Roman Reigns and The Usos.

At this point, the tension should ideally play into the Universal Championship feud, as the WrestleMania Backlash pay-per-view is just a couple of days later. A big surprise on SmackDown would be if The Usos end their alliance with Roman Reigns.

If WWE wants to continue Roman Reigns' dominance on SmackDown, then having both his cousins by his side would help that. If The Usos turn on Roman Reigns, then the entire dynamic of the Universal Championship match on Sunday will change.

#4. The Women's Tag Team Titles are on the line on SmackDown

The Titles are on the line in a WrestleMania rematch

The build to this Title match on SmackDown hasn't been exceptional. While it's good to see Tamina getting the spotlight after all these years, they did her no favors by putting her up against Reginald last week on SmackDown.

Either way, a WrestleMania rematch has been set for SmackDown, and most fans will expect Nia Jax and Shayna Baszler to retain the Women's Tag Team Championship. A big twist would be if Natalya and Tamina successfully capture the Titles, giving the latter her first piece of Championship success in WWE.

It's hard to say that she doesn't deserve it.

#3. The Mysterios to lose ahead of their big Title opportunity?

A big clash awaits on Sunday

Rey and Dominik Mysterio have the opportunity to make history this Sunday by becoming the first-ever father-son duo to win the WWE Tag Team Championships. Last week, Dominik Mysterio defeated one-half of the SmackDown Tag Team Champions Dolph Ziggler.

It would make sense for the SmackDown Tag Team Champions to stand tall ahead of their big title clash, especially since it seems more likely that there will be a Title change on Sunday.

Could the SmackDown Tag Team Champions shock the Mysterios before their big match on Sunday?

#2. Will Carmella make her presence known in the SmackDown Women's Title picture?

Victory for Carmella

We won't imply that the SmackDown Women's Title match on Sunday could change to a Triple Threat match, especially since there are enough Triple Threats on the WrestleMania Backlash card.

However, last week on SmackDown, Carmella defeated Ruby Riott in what was clearly mentioned as a stepping stone to a SmackDown Women's Title opportunity. With Carmella's victory, it seems like a small push might be coming for Bianca Belair's next pay-per-view program.

For now, Bianca Belair has to focus on the longest-reigning SmackDown Women's Champion Bayley. But could Carmella shock everybody and make her presence known to set up the next title feud on SmackDown?

#1. Seth Rollins continues to get involved in the Universal Title picture

Cesaro vs Seth Rollins on SmackDown

Last week on the Throwback edition of SmackDown, Cesaro defeated Seth Rollins in a WrestleMania rematch. This time, however, it wasn't clean. Thanks to a ringside scuffle that Rollins had with The Usos, he received a superkick that allowed Cesaro to pick up the victory.

There was a tense confrontation backstage between Roman Reigns and Seth Rollins. Even though the both of them are heels, Seth Rollins could somehow weasel his way into the Universal Title picture despite losing to Cesaro on two occasions.
