#3. Go to SmackDown: Challenge Kofi Kingston for the WWE title
Since AJ Styles has been drafted to RAW, there is a very good chance for Roman Reigns to be moved to SmackDown as the blue brand needs a big name after The Phenomenal One's departure.
The ones who have been watching Reigns ever since he made his first appearance on the main roster as a member of The Shield agree, that he was at his best as a member of the heel faction.
He talked little and was the muscle of the group, who could smash through anything. He also had the looks – still does – of a very serious man who could destroy anyone as a the bad guy.
However, going down that path wouldn't be wise as Reigns is finally getting cheered after a triumphant return from his battle against leukemia. In the meantime, turning Kingston heel would also not make sense as he is the most over Superstar right now.
As a result, Roman could challenge Kingston in a face vs. face feud. However, for this to work, a third Superstar who can play a heel's role needs to be added to the picture. This would just like how Dean Ambrose and Roman Reigns fought each other for the number one contender's spot for Triple H's WWE Title with Lesnar being the third wheel.
