#3 The Fiend vs Roman Reigns doesn't happen after WrestleMania
WWE has made a lot of changes regarding their WrestleMania plans. As per some reports, Roman Reigns was going to take on The Fiend in a Universal Championship match. Later, the plans were changed for reasons we don't know about.
Reigns is now scheduled to face Goldberg for the Universal Title and he is also the current favorite to win at ‘Mania. If Roman does win the title, WWE could be looking to book a match between The Fiend and The Big Dog at SummerSlam, where the former could reclaim his title. But if we assume that Wyatt is going to lose to John Cena at WrestleMania, a match with Reigns for the Universal Title doesn't seem likely.
Why would WWE grant a match to someone who lost two huge matches in a row? Wouldn’t it make sense for Wyatt to first gain some momentum and then challenge for a world title?
