#3 Roman Reigns overcomes all odds and defeats Brock Lesnar to a chorus of boos
There's no way you can end the biggest party of the summer with the Big Dog's hand held high without any significant alteration in his character.
Judging by how the Greatest Royal Rumble and WrestleMania 34, there's a slight belief in the company to book Roman Reigns as the Ultimate Underdog.
An Underdog that will overcome all odds this Sunday and finally slay the Beast. However, no matter how many times WWE continue to push Roman Reigns in the same way, the outcome will be the same.
Defeating Brock Lesnar clean at SummerSlam seems like a strong possibility and with the Beast Incarnate having the last laugh on the Go-Home Episode of Raw, the odds are stacked against the Big Dog.
Therefore, a strong possibility with the Big Dog defeating Brock Lesnar clean to win the Universal Championship will be met with a chorus of boos.
