5 potential main events for SummerSlam 2018 

2: Seth Rollins Vs Roman Reigns Vs Dean Ambrose

Which former Shield member would come out on top second time around?

Like Daniel Bryan Vs The Miz, this is a match that the WWE would be wise to wait for. Like Bryan Vs The Miz, though, there is every chance the company will end up rushing this one just to give SummerSlam a big money match.

There are numerous ways to set this one up, the first of which would be Reigns defeating Lesnar for the title. From there, you could go down any number of routes. Ambrose needs to return as a heel, so he could perhaps win Money in the Bank and cash in on Reigns before SummerSlam, or you could simply have the three men square off on an episode of Raw, leading to a triple threat at SummerSlam.

Like Bryan Vs The Miz, I would personally hold off on this idea until WrestleMania, but I can't help but think that the WWE had this match in mind when they went for their failed Sheild reunion at the end of 2017.
