#1 Roman Reigns vs The Authority
Well, during the main event of SmackDown Live this week, Roman Reigns paid a surprise visit to not only announce his arrival on SmackDown Live but he laid waste to both Vince McMahon and Elias Samson.
Thus, a potential feud against the authority could very well be on the cards for Roman Reigns.
Vince could put Roman Reigns against difficult odds each week on SmackDown Live only for Roman Reigns to overcome them each time. It could turn out to be an interesting feud and may put Roman crazy over among fans if WWE books it right. Also, it could then eventually end in Roman Reigns earning a shot at the WWE Championship against Kofi Kingston.
This would not only add that missing intensity and momentum behind his back, but it would also establish Roman as a legit babyface, as history has shown us on numerous occasions how superstars have faired tremendously well as anti-authority figures.
