#1 He will: He's a popular guy

Though fans may have differing opinions about Roman Reigns, one place he certainly is popular is backstage. As a locker-room leader, there haven't been many, if any, negative stories about Reigns' conduct backstage, as it seems everyone has something good to say about him.
The Big Dog has also been endorsed by some powerful figures, including Triple H and Vince McMahon. Whilst Reigns has feuded with both men and emerged on top both times, it's clear that the two most powerful figures in WWE are high on the former WWE World Champion.
With so much positivity about Reigns both from his fellow employees and the higher-ups in the sports entertainment juggernaut, don't be surprised if Reigns gets thrust back to where he was before his leukemia diagnosis very soon.
