#4 Roman Reigns
Currently working in an interesting feud on SmackDown Live, Roman Reigns should be kept far away from the Fiend on the main roster.
Even though the identity of his mystery attacker is still being investigated, bringing these two performers in the same ring could prove catastrophic for The Big Dog.
Looking at Roman Reigns' resume ever since The Shield broke up, the former Universal Champion is Vince McMahon's biggest project on the main roster and is unarguably the face of the company.
Since the creative would never want him to lose a feud, this could be a travesty for Bray Wyatt who has already lost multiple times to Roman in the past.
One cannot deny that this feud has 'WrestleMania main-event' all over it, but keeping the two apart for quite some time would be the best thing to do for now.
