#10 Shinsuke Nakamura
If he was unhappy in WWE, you wouldn't know it. He doesn't spout off much on social media or in interviews but he shows up for work when they ask him to.
Nakamura has a contract that expires at the end of April, and companies like WWE, AEW and NJPW will certainly be looking to sign him.
WWE might be confident that he'll stay, otherwise, they wouldn't have taken the US Championship off him so soon after regaining it.
If that turned him off, however, it wouldn't be hard to envision him either going back to NJPW as they would likely take him back no questions asked.
All Elite Wrestling would be an interesting option because of the uncertainty behind just what we can expect to see.
We've seen talent and heard comments from a lot of people, but until the product is something tangible, it will be hard to see how things will turn out.
Nakamura seems like a laid back guy, so as long as he can surf wherever he's wrestling, I think he'll be happy.
WWE would be losing a huge international presence if they failed to resign him, so maybe they are underestimating just how good things are for everyone in their company.
