Though the WWE underwent a "Superstar Shake-Up" in April, there are already rumors about a second one happening in the near future. It's already expected that Kevin Owens and Sami Zayn will head back to the Raw brand, which means a number of top-tier stars may have to head over and don the blue.

Though many superstars are fine where they are, a number of wrestlers are lost on their current brands. Some of their feuds haven't worked, and some of them are getting lost in the shuffle.

If another Shake-Up is in order, there are a handful of stars that need the switch badly. Here are five WWE superstars who desperately need a move to the other brand.

5. Baron Corbin

The United States Champion has done an excellent job filling in the mid-card role, it's just that Baron Corbin doesn't have many suitable feuds left on SmackDown. He's already gone up against Sami Zayn, Shinsuke Nakamura, AJ Styles, Sin Cara and Kevin Owens. So where does he go here?

Corbin could use a move to the Raw brand, where feuds with The Miz, Bray Wyatt, Braun Strowman, Enzo Amore, and Big Cass (when he returns), could be enticing. Corbin has also been somewhat irrelevant at times, as SmackDown focuses too much on Styles, Zayn, Owens, and Jinder Mahal.

For Corbin, a change gives him the chance to get over even more and possibly launch into the main event. He's stuck in the mid-card and simply deserves better.

4. Sasha Banks

The Legit Boss was once being pushed as the face of the women's division in the WWE. But the rises of other stars like Bayley, Nia Jax, and Alexa Bliss quickly pushed Banks out of the big picture. Throw in the arrival of Asuka, and Banks is simply lost in the cards of all the talented Raw women's superstars.

Banks has already teased at possibly coming over to SmackDown too.

Banks has a prime opportunity to re-enter the main event picture. On SmackDown, she could feud with other top-end stars like Natalya, Becky Lynch, and Charlotte. A possible heel turn could also be in the cards for Banks, who does need a major change.

She's done all she had to on Raw, but now it's time for her to become the face of the blue brand. Raw has too many other women's superstars to focus on.

3. AJ Styles

Styles has been on SmackDown since the 2016 WWE draft, but it's more than time for him to start engaging in new rivalries. His feud with Jinder Mahal better end soon (please, for the love of wrestling fans), and then who's next? He's already had his feuds with Owens, Randy Orton, and John Cena.

Styles may be the biggest superstar on the WWE roster right now. Bringing him over to Raw means a possible feud with The Shield, or even guys like Braun Strowman or Finn Balor— who wouldn't love a rematch of their TLC bout?

With Styles hinting that his WWE career could end in two years, WWE has to maximize the opportunity to have the Phenomenal One go up against every star possible. He's done his due on SmackDown, now he deserves another run on WWE's top show.

2. Samoa Joe

Is it just me, or has Samoa Joe been slightly misused by the WWE since coming up to the main event roster? Yes, he did have a knee injury and missed almost two months. But he was irrelevant for the five-on-five tag team match at Survivor Series, and WWE doesn't appear to have much of a plan for him right now.

With his in-ring ability and label of being a true butt-kicker, Samoa Joe should be the face of SmackDown now. He's not out-shining The Shield, Brock Lesnar, Finn Balor, or Braun Strowman. It just isn't happening.

Joe deserves a nice WWE Championship reign and should be the face that runs the place...somewhere. SmackDown gives him a nice change, so please do it WWE. No more keeping him below the other top guys.

1. Shinsuke Nakamura

What a travesty. The WWE has completely, without a doubt, unquestionably and surely failed to use Shinsuke Nakamura to the best of his talents. Like, how?

This guy may be the top in-ring wrestler NOT named AJ Styles right now. He's gotten over with the crowd, no problem at all. But oh, guys like Mahal and part-timers, John Cena and Shane McMahon need the spotlight more. Come on, now.

Nakamura has all the ability to be your top guy. It's clear SmackDown won't give Nakamura that opportunity. At this point, Plan B must include him going to Raw. He could get his chance there and start feuding with their top stars. At this point, why should we believe Nakamura will shine in SmackDown? It hasn't happened.

Raw time.
