#4 They're probably going to have another angle during the show
Given that they've been putting so much emphasis on the angle and Roman Reigns, Samoa Joe nor anyone else involved is on the card - it's almost a guarantee that we're going to have another angle of sorts during SummerSlam.
SummerSlam, as you know, has been increasing in length and runtime over the past four years and we're probably set for a five-hour main card, if not more. Given that there are going to be so many matches, there will be a place for them to run the angle on the show.
It's going to be extremely interesting to see how they go about running the angle and whether or not we'll see the likes of Daniel Bryan and Rowan will be involved in any capacity. It's an angle that we believe WWE fans should genuinely be excited about.
