#1 Roman Reigns vs Elias (with Vince McMahon)

During the main event of SmackDown Live this week, The Big Dog Roman Reigns not only made a surprise visit to announce his arrival on the blue brand but also went on to beat up Elias and Vince McMahon.
Thus, a potential feud between The Big Dog and Elias seems totally on the cards for the coming weeks. However, Vince could add a little twist in the tale if he decides to add himself into this feud.
Look who just shut down all of Tony Khan's critics! More HERE.
While Elias could take care of in-ring stuff, Vince McMahon could put difficult odds against Roman Reigns only for Roman to overcome them each time.
While this would not only put over Roman Reigns among the fans as an anti-authority character, it could also establish Elias as a legit heel. However, it would be interesting to see what role does Vince McMahon play in this feud. (Because you don't get away after laying hands on your boss).
