#3 AJ Styles or Shinsuke Nakamura
It was briefly mentioned by Sheamus on this week’s Raw that he has heard rumours that a Superstar Shake-Up might take place after WrestleMania 34, just like it did a week after WrestleMania 33 last year.
If it happens, then we can expect some major stars from Raw to make their way over to SmackDown Live (let’s face it, the blue brand desperately needs some fresh talent), and Seth Rollins is one of the most popular guys on Monday nights right now.
As we previously mentioned, Superstars are likely going to need to be involved in title storylines to feature regularly on PPVs in future, so it’s not out of the question that Rollins could move to SmackDown and immediately challenge the winner of the WrestleMania match between AJ Styles and Shinsuke Nakamura for the WWE title.
