#2 Roman Reigns has unfinished business with Braun Strowman, and one has to assume that Bray Wyatt has unfinished business with The Big Dog
Listen, Roman Reigns vs. Goldberg was supposed to be the big marquee match at WrestleMania, shortly after Bray Wyatt lost the Universal Championship, but Roman Reigns had to pull out at the last minute when the world went crazy. Braun Strowman would replace Roman Reigns in the match, and go on to win the WWE Universal Championship at WrestleMania in a short and sweet match. Of course, Bray Wyatt would go on to have quite the match of his own against John Cena at WrestleMania, a match that Randy Orton put over in the interview linked above and below as well.

So now, Bray Wyatt has a bone to pick with Roman Reigns, because of their history and also because of his actions at SummerSlam.
And Roman Reigns has a grudge against Braun Strowman for taking up his spot and his moments under the spotlight. This should be very interesting indeed.
