#1.) Roman Reigns
Roman Reigns can still hold the claim of being the uncrowned true Universal Champion. However, being on a different brand means that there is a different World title to compete for and just because he’s not in the World title picture now, it doesn’t mean he won’t be soon. Reigns, to his credit, has done extremely well since his inspiring return from leukemia and it only seems fair that he gets into the World title picture again.
Whether fans like it or not, Roman Reigns will be WWE Champion and beating Kofi Kingston would still make him a worthy champion.
