3 potential feuds for Roman Reigns on the SmackDown roster
#2 Roman Reigns vs a returning Bray Wyatt
The architect of Wyatt Family, Bray Wyatt, has been missing from WWE TV since he incurred injuries in a minor car crash last year. However, he is not only medically cleared to compete in the WWE ring, but WWE has been hyping a character change for Bray in the last couple of weeks. Thus, a potential return of Bray Wyatt is not that far.
On another note, while Roman Reigns did manage to get a major win against Drew McIntyre at WrestleMania 35, there is not much momentum behind him (given he was out from WWE for a considerable amount of time). Thus, given Roman Reigns has minimal momentum, a solid and gripping feud with a returning Bray Waytt could do wonders for him.
It would not only draw a lot of eyeballs, but it could establish Roman Reigns as a legit babyface and put him crazy over among fans (if he is not already). WWE could then utilize that intensity and momentum to launch him in the main event scene against Kofi Kingston.
