#1 The Rock and Roman Reigns could create a dream match at WWE WrestleMania

Yes, there are various factors that could prevent The Rock from returning to the ring. His busy movie schedule can be difficult to plan around. But there's still a possibility that he could return to WWE. Undoubtedly, the best opponent for him would be the current WWE Universal Champion, Roman Reigns.
"The Big Dog" has taken on new heel character in recent months. This persona has been largely built around his status as the head of his famous wrestling family. The Rock could be the perfect challenger to "The Tribal Chief" on the legendary stage of WrestleMania.

Reigns' focus on the familial part of his character lets this story write itself. The Rock is Reigns' cousin, so he could step up to defend the family. From there, a WrestleMania bout would be a natural and seamless culmination if the cards fall the right way.
This match could be the perfect way for The Rock to officially pass the torch to Roman Reigns and cement him as WWE's biggest star.
